This is the animation of Whitney's Music Box. When i saw this in a gif, i couldn't resist. I had to make an interactive version to pause, slow it down, and speed it up.

There are two ways you can modify the revolution speeds. Left/Right keys gives you a uniform speed change. Up/Down is more interesting as it makes the outer/slower dots go in the reverse while the inner dots are still slowing down.

Made using Phaser Engine (and Led Zeppelin albums I,II and III ;) ).
