Some clever guy called Lars Pontoppidan has come up with a version of Tetris on an Oscilloscope.
The game is just Tetris marathon with a gradually increasing speed, and the score is simply the number of lines removed. The speed, however, is not related to number of lines removed, but to the number of line removing rounds – each time dropping a brick causes lines to be removed. So, to get a high score, one must zap a great number of lines each time, and of course be able to control a high speed.
Check out this video of it in action.
