Art in the mouse?

I ran across this site which offers an interesting program which can record your mouse movements across your screen as well as where it sits (the large black circles).  I tried it for several hours as I mixed music for Luke's act at Davis Hall.  when I looked at the picture it created from my movements, I could visualize all that I had just done and accomplished by looking over the movements and patterns created.  I could tell where I frequently moved objects on screen and manipulated portions of the songs I was mixing.  The image told a tale, even if it was one that only I could understand.  Here's the link to the site, check it out sometime: http://flowingdata.com/2010/02/09/track-mouse-activity-on-your-computer/
