This one makes me imagine that the "probability clouds" for sub-atomic particles could actually look like this...or a beautiful and better frequency analysis tool for music and audio with currentTime being width/2 ... I'm really glad I found your articles, they are fantastic and inspiring, thanks for sharing them!
