If you like this kind of stuff go to Siggraph and visit the emerging technoligies section.  Very fun stuff to play with while waiting for the next conference  

Not display related but in 2006 they had a really cool Ferrofluid Sculpture

Shows like CES also have an emerging technoligies section but its more likely that things shown there will go to market.

Looks like something that could be easily done on an iphone

There was a game that used this tech for the gameboy color, it was called Kirby's Tilt and Tumble. I own it, it's awesome.
