This sketch belongs to Sam Becker and is the first sketch on my website for the Lovett Doodle project that actually works. The only thing missing is the sound library which processing.js does not support currently but I think there is a workaround, and in this version of Sam's sketch there is no restart button but you can reload the page to get the sketch to start over. Clicking and holding the mouse makes the letters move to the right side of the screen.
