This is a video of pianist Sonya Belousova performing the Tetris theme on a custom built pinball machine inspired piano. If you're interested in winning the piano (or the one used in their Akira video, which I also posted after the jump) you can contribute to their Indiegogo campaign, which they're using to help fund future themed videos (including The Legend of Zelda, Halo, Sherlock, Cowboy Bebop, Nightmare Before Christmas, Super Mario Brothers, Star Wars, Lord of the Rings and Disney Themes). Also, for you L.A. locals, you may recognize this video was shot at Blispy Barcade, where I've currently got the high score on Joust. Can you beat it? SPOILER: No you cannot. At least not without a fight afterwards.
Keep going for this video, the Akira inspired video, and their crowdfunding information video.
Thanks to Alessandro, who agrees a piano built with arcade buttons instead of keys would also be cool.
