This is a fun little video from kokokaka is not something that you really watch, but rather use – it allows you to actualy play a video piano interactively. The video uses the YouTube annotations feature to jump around in the video based on what piano key is clicked.
Genius. There are a couple more playable instruments around as well. After fiddling around with this YouTube piano, I can think of all sorts of other strange and interesting applications for this sort of concept.
