This is the Space Explorer mouse, which is quite popular in the 3D design field. It certainly is weird looking, but once you master it, you will be able to click on a single pixel if necessary. Who needs a big old "X" in the top right corner of the window when a pixel would do just as well?!!
Introducing the Soap, an optical mouse with mid-air functionality. It supposedly "consists of an optical sensor device moving freely inside a hull made of fabric." Yeah, I know, I have no idea how you control the mouse precisely while everyone around you is splitting their seams laughing at you trying to control your mouse cursor with a ball of cloth in your hand!

This finger-mouse straps onto your index finger and uses an optical sensor to track your pointing. You click with your thumb, which also controls a scroll wheel!
