Micro Tetris
Jeroen writes "Students from the Vrije Universiteit Amsterdam used a so-called 'optical trap' to construct a version of Tetris that measures 25 x 20 micrometers. Blocks are constructed from tiny glass beads and all the action takes place in a waterdrop under a microscope. Considering the equipment needed, this must not only be the smallest, but also the most expensive Tetris clone around. A short description and a movie can be found here."
If you take 42 of those things and make a beowulf cluster of those...something will happen !
It'll distorse the universe with nanowaves or something. Or maybe all the gameboys in the world will explode in astonishing Tetris music concert... I don't know.
But please, don't talk about this to George Bush
