Interesting idea, but it's a shame they didn't put a little more effort in to the device and actually have it work like real Tetris by making completed lines disappear. That could have been done fairly easily, I think, and would allow parts to recycle. The video itself was also a disappointment - so incredibly dull! Aspiring videographers take note; don't bury the lede by only letting people watch the "exciting" part of the video after they've suffered through two and a half minutes of really boring stuff, and if you've only got a minute worth of material, don't make a 9 minute long video.
