I found this really cool little java program from Anatoly Zenkov (famed designer of MTV Russia, perhaps? Check out his website) that tracks where your mouse moves and how long it rests for. You can download it here: dl.dropbox.com/u/684632/mousepath.exe.zip (PC) dl.dropbox.com/u/684632/mousepath.jar(Mac), or you can just search Mousepath in Google and find some neat looking pictures. In the picture above, I’m pretty sure the enormous black circle is from when I left my computer on over night.
