Mr Doob

When playing with Mr Doob, I found it particularly interesting when I could control the image.  For example, I was playing with the Sphere on Mr Doob and in whichever direction my mouse moved, the sphere moved and changed color.  I had complete control of the direction and speed of the sphere, with a simple swipe of my mouse.  While experimenting, I had music playing and a one point I tried to collaborate the image's movements with the music.  It was an experiment that produced me with a curious feeling!
