World's First Ice Touchscreen Made by Nokia

A team at Nokia in Finland has created the world's first ice touchscreen. Though it is not a practical device, of course, but the screen is being seen as a step towards an era in which the surfaces around us gain computing capabilities. The team used a tonne of 25-centimetre-thick river ice, and used a chainsaw to cut it into 50-centimetre-square slabs. They used these to make a 2-metre by 1.5-metre ice wall and then blasted the surface with a heat gun - more typically used for stripping paint - to create a smooth surface.
"This was a playful experiment, but one that we think showed interactive computing interfaces can now be built anywhere," says Jyri Huopaniemi at Nokia's research lab in Tampere, whose team built the touchscreen, dubbed Ubice, or ubiquitous ice. Finland has a tradition of building snow and ice sculptures during its long winter. It was these that inspired the device, says Antti Virolainen, a member of the Nokia team. "We decided to see if we could make an ice sculpture that was interactive." 
The Nokia research team did basically was take blocks of ice, stack them up use heat guns to join them together and then using infrared, optics and some electronics to create the World’s first touchscreen made from ice.
"Playful experiments like this are important - people really liked it," says Huopaniemi. "New forms of interaction, sensing and content delivery for future mobile devices could come out of it."
