Architect of the Lego House built for Top Gear presenter James May, Barnaby Gunning, has sent us pictures of the construction progress so far. We'll post more as we get them.

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 .
