Seeing as how much time is spent using a mouse, it would make sense to buy one that is as comfortable as can be and is as easy on the eyes as it is on your hand. Designer Joey Roth is planning to build a mouse that is all that. 

The Felt Mouse will—surprise, surprise—be made out of various layers of felt, giving the user a much softer clicking experience. We're not sure how much someone would like it after using it for a full work day, but once he finishes building 'em we'll try it out and let you know.
