Manikins used for dental training are either deep into uncanny valley (creepy) territory if they try and look at all realistic, or just plain terrifying in their more abstract incarnations. A lot of this is just becuase (a) people are very good at interpreting faces and anything face-like seems possessed, (b) dental manikins have to bare their teeth so often have bizarre expressions. Anyhow, they are quite interesting, particularly the vintage metal ones which are a nastily grotty and beaten up.

Some machines that punch, stamp, strike or print money. What everyone needs these days, and what central banks will be using a lot of. You may be amused to find out that even the J-98 Bank Note printing press is made in China.

Although there are many ironic underwater technologies that got there by accident, such as planes and trains or by design, underwater escape training helicopters, there are also mail boxes, telephone systems, cars, motorcycles, kayaks (yes underwater kayaks) and air conditioning units that are there just to mess with us. Here are the most surreal we could find, vote for your faves.

Several star architects such as Herzog and de Meuron and Rem Koolhaas have produced building designs that have jutting out and cantilevered components that give the overall impression of a giant game of Jenga. The New Museum on the Bowery in New York, is the latest addition to this genre of minimalist deconstruction. But the most interesting Jenga building is an obscure, former Soviet ministry in Georgia, which is quite mad.

As people blow each other to pieces, daily, on the planet below, the silently floating Hubble telescope seems to represent everything great about humankind. Here are our other favorite telescopes.Update: Have been in continuous operation since 1963, the Arecibo project is in danger of closing due to cuts in funding. Jonathan, who is a researcher working at the Arecibo dish has posted a link in the comments to its website where you can donate or voice your support. http://www.arecibo-observatory.org

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.

Gym equipment has a habit of making people look stupid, like that weird guy on TV with the pony tail and the abs machine. These machines are the zenith of fitness absurdity - teaching you to swim on dry land, anywhere. Handy if you are an Olympic swimmer holed up in a hotel room, waiting to be airlifted into Beijing when the smog clears.

The same week that former underdog, Apple became larger than Microsoft, the company that it infamously portrayed as Orwellian in commercials for the launch of the Macintosh, Jon Stewart suggested that it behaved like Big Brother towards Gizmodo, with police searches and assorted high drama. All over a leaked iPhone prototype.This roundup of a dozen examples shows that gadget leaks are commonplace, except for Apple (although even the iPhone prototype that is causing such brouhaha appears to have been leaked in Shenzhen). This secrecy is partly understandable as few companies innovate in terms of design the way Apple does. Most of the example below are either highly derivative of Apple designs (Dell tablet, Motorola Tao etc.) or non-groundbreaking (Lenovo T400s, Blavkberry Pearl 9110).Perhaps Apple should take a leaf out of Microsoft’s book, going forward. Instead of trying to keep things secret, Microsoft are rumored to have a strategy of creating multiple fake decoys, leaving it impossible to know whether a leak is the final version.

Alain Robert, known as Spiderman, climbs the tallest buildings in the world, without ropes. Last summer he famously scaled Frank Genry's new tower for the New York Times, in Midtown Manhattan. Here is a list of video footage of him climbing a dozen different structures.

Beautiful working model Stirling engines are a favorite of the Steampunk style, because these efficient engines use external flame heat as an energy source, combined with Victorian brass or steel mechanisms.But they have an added benefit, in that their workings are entirely intuitive and help people easily understand the principals of cylinder engines in things like cars. Here are a collection of videos of some of our favorites, some, but not all, 'Steampunky', in action.

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.

Burning man, which currently rages in the Nevada desert, is Mecca for art cars. America is the capital of modified cars, since rules about what you can do to your car and it still be street legal are less stringent than most other developed nations. Custom vehicles are a cultural expression of individuality.There are many categories of art cars, but our favorites are where a mundane, ordinary vehicle is completely covered in a single material or item. Here are some of our faves.

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.

Considering that super thin, flexible, touch-screens and large capacity solid-state storage are just around the corner we expected to find many more examples of interesting concept designs for laptops. Here are the best that we found, however this is one case where we think the realized products will outstrip the concept designs.

Something went very wrong in the 18th century. A 100 year long attempt to wear the most ridiculous artificial hair involved dandies sporting macaroni and culminated in Marie Antoinette’s utterly mad ship wig. The last vestige of this is the bizarre tradition of British and colonial judges who continue to don 300 year old clothing in a profession which is supposed to be rational.

Ever since the strapline ‘Nicholas Parsons is the neo-opiate of the People’ graced a concrete roundabout in Harrow in the 1970s, I’ve been a fan of sardonic or facetious textual graffiti. Sadly, my all-time favorite, the simultaneously mindless and profound spaying of the word ‘wanker’ above a bronze statue of Freud in London’s Swiss cottage, couldn’t be found, however here are 15 choice favorites from the many collections of these around the web.

It seems like oil cleanup includes some of the most basic and advanced technologies, from literally hoovering it up, to skimming it and burning it, using oil eating bacteria and swarms of Roomba style oil cleanup bots.

There have been four core audiences for Apple along the years, the original Mac for graphic designers and Desk Top Publishing, the OSX based machines which lured developers, the iPod which brought Apple into the consumer market with lifestyle apps, and the original Apple II which became a computer widely used in schools.Looking at these old commercials from the late 70s and 1980s, including the first ever Apple ad (which was a store ad not produced internally), you can see how much they were aimed at kids. Even then, there is a faint glimmer of the artistry of later Apple ads which aimed for high ideals and changing the world

According to Bismarck the two things you should never see being made are laws and sausages. Here we reveal the machines involved in the process that is less stomach churning - it involves taking meat and making it into a brown paste then putting it into a colon, traditionally pigs intestines but now plastic. The irony of this being the exact reverse of eating and pooping, obviously hadn't been lost on the German general.There are no more distressing images here beyond what you'd see in the meat section at the supermarket (merely gross ones), but the clip for the Advanced Meat Recovery System which is accompanied by some smooth dinner jazz and whose opening caption reads ‘preparing the beef neckbones with a bandsaw' wins a prize for lack of sensitivity.
