USB Desktop Christmas
This tree is perfect as it never sheds its needles so no cleaning is required, and it comes with is own fibre optic lights and decorations.
you actually plug this into the computer and she does her thing
Creative I like this one....
Here is a great way to practice your DDR moves at work. Awesome time waster and desk decoration. You keep up with the lights and it will get progressively more difficult. Try not to get caught dancing on the job!
connect whack a mole into your usb port and play when ever, where ever you want
