Some people take paintball very seriously, and the boundary between harmless fun, unintentional irony and plain creepy is blurred. Here are paintball teams that look like outright militia, and some are. They include a church team in full combat gear a German group that re-enacts LAPD swat team offensives, and three very disturbing teams: a Japanese paintball re-enactment of the Yugoslav civil war complete with Serbian militia uniforms; an US vs Iraq shoot em up in Jordan and a sinister third Reich Team with Eagle T-shirts. Vote them down.

The Saturn V rocket was something the size of a skyscraper could survive being thrown into orbit, undamaged. 40 years after the Saturn V powered trip to the moon, nothing as powerful exists today.

Years ago Airfix made a model of a Saturn V which I lusted after as a kid and Revell have now re-released their original 1:96 version and a 1:144 one which is the same size as the old Airfix. We tracked down the best Saturn V models that you can buy or have been built, culminating in auto repair man, Steve Eves’ completely insane home built 40 foot high, 1600 pound monster which he actually launched, in April.

Being tall and thin means that one of the common but nevertheless unusual uses of old silos is to house climbing walls. Old silo structures, from underground missile silos to towering grain stores are often interesting pieces of industrial archaeology and make unconventional architectural conversions.

The interior design of Sweden’s giant nuclear bunker.

In the mid seventies, when ABBA topped the music charts, Sweden was just putting the finishing touches on its giant civil defense nuclear bunker outside Stockholm, called the Elephant.

Traditionally neutral Sweden made this a priority due to its close proximity with Russia, but the Elephant is unlike any other cold war bunker – because it looks rather like an underground IKEA.

In order to prevent claustrophobia, fake horizons were painted on the walls of recreation areas, with green below and blue above, representing sky and grass. Even lamps were painted yellow to represent the sun. In the business parts of the bunker, such as briefing rooms and control rooms, shades of gray relieved by red were used.

Unlike other bunkers which used the same tactics, with murals of mountain or countryside scenes the obsessive schematic nature of the Swedish bunker is like a children’s bedroom in hell.

Urban explorers have visited and documented the Elephant bunker. Here are our picks from a wonderful set by Bill_R on Flickr. Click through any of the pictures for more.

A perfect example of nothing dating like the future, the garbage can robot is a retro-futuristic cultural icon. Some of these were cheap props for cheap movies, but others were serious visions of the future. If nothing else they demonstrate quite how imaginative the Metropolis robot that stands the test of time was.

The original British Secret Service headquarters was just that, secret. But the increase in importance of electronics meant that it was more important for a building to be invisible to electronic eavesdropping. as such the current M16 HQ in London is about as obvious a giant sign saying ’secret building here’, yet it is enclosed in a giant Faraday cage to protect its communications.

Not all Intelligence agencies have had a discrete architectural past, Franco’s House of Screams, or the Soviet Lubyanka are demonstrably terrifying. Mossad’s HQ, until the 60s or the current Australian Secret Intelligence Service look quite modest compared to the hardly known Ministry of National Security of Azerbaijan, which houses its intelligence service, in a large and monolithic building of dramatic proportions.

The Highline is fashionable in every sense. A park inspired by one in Paris, a combination of Euro chic, treehugging sanctity and hipster industrial grunge.

But it sits above ground, shovels people off the streets via stairs which cyclists can’t use and leads from nowhere to nowhere. In addition, little money ha been spend on the dark spaces underneath, which could easily negate any benefit provided above.

The designers involved are great and there are nice touches, but could it have been better just to have torn it down and created something at street level. Such talk is heresy, but here are 9 reasons why we are disbelievers.

Britain is probably the only country in the world where electric vehicle use is declining, due to the rapid disappearance of the electric milk delivery vehicle, or milk float.

Until recently it was common place for milk to be delivered to almost every house in the UK, daily. Presumably in order to secure the national flow of tea. To achieve this a vast army of distinctive, cheap looking, sluggish, electric utility vehicles paraded suburban streets.

Here are some different varieties, including new concept vehicles and milk floats from movies, all preserved for posterity.

This year the MIT class ring, the Brass Rat, hides a hackers’ diagram of a subterranean campus wide tunnel network.

Networks of secret passages and tunnels have been built on a giant scale, from components of the Maginot line to the Viet Cong Cu Chi Network. Others perform a peacetime function, such as the half mile tunnel network H.G. Dyar built under his Washington home, as a hobby, the passageways under Disney’s Magic Kingdom or the unbelievable 5000 year old Lizard People tunnel network under Los Angeles that the L.A. Times published a diagram of during the depression.

Here is a collection of our favorite tunnel network diagrams, drawings or models.

The most impressive neon districts in the world include Tokyo’s Ginza and Shibuya, Osaka’s Dotonburi which was the inspiration for Blade Runner, the worlds largest shopping street, Nanjing Road in Shanghai and, of course, Vegas and Times Square. Bangkok’s Soi Cowboy district (named after an American who opened one of the first go go bars in the 70s) deserves inclusion on account of its unpleasant strangeness, with live elephants paraded up and down the pink neon streets.

Most dramatic of all, however is Hong Kong where the entire skyscraper cluster is animated for 15 minutes as part of the worlds largest light show.

Vegas and Times square deserve double mentions as they are more famous for iconic signage which has since been demolished or taken down. We have included footage of both past and present.

Although the classic welcome to Vegas sign by Betty Willis has been preserved, many of the famous signs lie in the Vegas neon boneyard and we have included a movie made by urban spelunkers who broke into the yard to explore it.

To mark the 800th anniversary of the famous London Bridge, the Royal Institute of British Architects has launched a competition for designs of an inhabited bridge.

The current London Bridge is not the Victorian Gothic Tower Bridge, as many people believe, but a rather bland stone one. Its predecessor was also uninteresting and was bought by mistake and put in the Arizona desert. But the original London Bridge was a cultural icon, a bridge covered in buildings.

Inspired by the competition we have put together a list of the most interesting inhabited bridges, from surreal single house bridge designs to Zaha Hadids sleek Zaragoza Expo bridge .

Just how much of the human body can you replace or augment: seemingly everything apart from the tadpole like remnants of the brain and spinal chord.

Bionic eyes, ears, hearts, lungs, kidneys, livers, hands, feets, legs, arms and skin are now real science rather than concept designs. For this list, we have gathered together as many real devices including commercially available products rather than concept designs or imagery that appeal based on gimmick value. The one exception is the tooth and ear cellphone implant which is feasible today.

An interesting idea is how the notion of a cyborg might change (often imagined as fusion of mechanical and electronic technology with human biology), since many of these devices use technology that is itself principally biological, such as stem cell lines in the bioreactor liver or artificial skin.

Futuristic megastructures are ironically a thing of the past. An architectural style dubbed supermodernism that flourished in the late 60s and early 70s. Despite the seemingly tongue in cheek nature of projects by Superstudio which threatened to engulf Manhattan in a giant concrete snake or Archigram who proposed plugin and walking cities, these projects have had an enormous impact on architecture. They are the inspiration for both fictional and real projects, from Blade Runners Off-world, to the Pompidou center and continue to influence master-planning projects today.

The world is truly a small place when the Inuit, Bedouin tribesmen and Tibetan nomads all have HBO. The wonder of satellite transmission creates a perfect juxtaposition of old and new as space age technology meets traditional lifestyles than haven’t changed in centuries – apart from the ability to watch Battlestar Gallactica in Outer Mongolia. Here are ten examples of traditional dwellings with satellite dishes.

Despite the title of this list, several of these housing projects were designed by some of the world’s most famous architects and lauded at the time. The undeniable squalor of 19th Century slums combined with modernism to produce and attempt to clean things up and create a crystalline utopia. The end result was often an anti-septic vision of hell, a place devoid of organic spaces and evolves social interaction.

The architectural crime that started with Corbusier’s insane proposal to demolish the historic center of Paris and replace it with something like the worst of the South Bronx and culminated in the White and Black racially segregated human silos of St Louis’s Pruitt-Igoe, continues to this day and even as middle class, owner-occupied dwelling such as those in Hong Kong. Its principal feature is de-humanizing alienation. Vote for your worst…

The name Chrysler will be remembered if no other car is produced, in the automobile inspired skyscraper that is the pinnacle of American machine-age design.

The Chrysler building is the tallest brick (steel re-enforced) building in the world but it is fundamentally modern, a triumph of both technology and design. Steel gargoyles were modeled on 1929 Chrysler automobile hood decorations and radiator caps and the earliest stainless steel cladding covered the stepped, Thai Princess-like crown. The Chrysler’s spire was unveiled in less than an hour, to make it the tallest building in the world and the first the first structure more than 1000ft high.

Here are a selection of iconic views and details of the Chrysler, what I believe is America’s most important building, and an important milestone in the history of technology.

At first sight these buses may look horrifying, like miniature cattle wagons full of children. But they are a feature of a type of culture that is different from America where yellow school buses shuttle children often over large distances. This culture, common throughout the world is one that has grown organically, where distances are short enough to be cycled (where litigation is minimal!) and where homebrew transportation is common.

In some ways these buses are a marvel of practicality and an interesting Oobject.

Phoropters, the gadgets used by opthalmologists to test your eyes look like the most spectacular binoculars you have ever seen.

The traditional complex mechanical versions are technological works of art made by lens makers such as Bausch and Lomb and have the design quality of a classic vintage Leica camera. Only now are these marvelous gadgets slowly being replaced by simpler looking, wireless, digital versions which relay data to a computer for image analysis.

If you thought the Bullet train was the fastest thing on rails, you would be wrong – more than 6000 miles per hour wrong. Rocket sled test tracks were originally designed for the V2 in WWII and can reach up to 6400 mph.

They were made famous in the 50s when Lt. Col John Paul volunteered himself to test a 200mph track designed for crash test dummies, called the Gee Whiz. The test was intended to show the effects of deceleration in a plane crash, where it was assumed that nobody could survive more than 18G. Strapp survived an unbelievable 35G.

More recently a rocket sled was featured in Indiana Jones and the Kingdom of the Crystal Skull.

However, the lasting legacy of the Gee Whiz test is Murphy’s Law, coined after a real engineer called Murphy who worked briefly at Edwards Air Force Base on the test track.

Heart rate monitors connected to an ink plotted graph are a staple of movies and TV and they usually come in beautiful portable versions by companies such as Lafayette Systems, making them a classic spy suitcase gadget.

Polygraph lie detectors are widely believed to be useless quackery, no more effective than a Scientology Dianetics machine, but they are commonly used by law enforcement and government agencies, usually in the US and are an anachronistic cultural legacy of the cold war.

Today, the classic analog polygraph is being replaced by much less interesting computer versions.

Somewhere between a damp cloth and a full NBC gas mask lies the often unintentionally hilarious looking smoke hood.

Promotional material for these items is a particular source of amusement, combining the creepy looking imagery of people wearing strange plastic bags on their heads with the utterly normal attire of office workers or suburban mums. The effect is like catching your boss wearing fetish bondage gear.

Aside from the fact that vintage massage devices look less like smooth sensual objects than giant, terrifying dental machinery they are possibly the worlds best source of laugh-out-loud, euphemistic advertising copy.

Here are a range of our favorite Frankenstein devices with some classic product names, such as the Handy Hannah Vitalator; Niagara Cycloid-Action Cyclo-Massage; Stim-U-Lax Junior; Bonger Body Massager, Magic Fingers Motel Bed Massager or our personal favorite the Chic [sic] Glorifier.
