This little mouse is sure to bring a smile to the face of other people at your office, even if the smile originates as they wonder what exactly would bring you to buy something like this. If you are still feeling in the holiday decorating mood, the folks over at Thanko, the destination for weird USB gear has the thing for you.

This is a normal (sort of) USB mouse that is clear and has water inside the mouse body along with a snow man and the fake snow we all know and love from those cheap snow globes we get as gifts when family and friends go on vacation.
Plug the mouse in and different color LEDs make the water inside the mouse glow seven different colors. The buttons of the mouse a replete with a smiley face to spread the cheer further. The resolution is 800 DPI and the mouse needs either a USB 1.1 or an USB 2.0 port to operate. No external power is required for the light show; all functions of the mouse are USB powered.
