Here's something kinda cool that should probably be standard issue with every computer: a USB Yoda buddy. I think this is the reason computers were actually invented.
This little item clips to the top of your monitor and is powered via a USB port. and you can program him so that his lightsaber activates when you type certain keys.
The downer: It's made for the Japanese version of Windows/XP Vista so there's a chance it won't work on American computers or other operating systems.
