fantastic idea!  crap quality.  Someone needs to swoop in with pro made critters and trademark that mess.  maybe add photog operated moving ones, like those kids toy jumpy spiders?

Second the Logitec Performance Mouse MX.  It's very comfortable, has a thumb switch that changes mouse pointer response (good for PS work) and the center wheel "hyperscroll" function is amazing!  it's like a skateboard ball bearing, and once you get used to it you can go from end to end of long documents in a hurry.
