ThinkGeek has some really cute USB devices to make the mundane more fun. They have a 2 GB USB storage drive that transforms into Tigatron. Trypticon and Grimlock will transform into 800 dpi mice with 3 buttons and a click wheel. They’ll work with Mac OS X and with Windows 2000, XP, Vista, and 7. These Transformer devices are made by Takara Tomy of Japan. ThinkGeek seems to be currently out of stock on Tigatron, but either of the laser mice can be yours for $59.99.
