What to Get My Geek for Valentine's Day?

A reader writes "Help!!! I've been dating my geek for three months and I'm in a bit of a dilemma. So I thought I'd ask the men of Slashdot what they would want as a Valentine's Day gift. I'm looking for something out of the ordinary that will knock his socks off. Somthing clever, crafty and unique. The budget is $100. My geek's interests are typical geek fare, games, computers, music and gadgetry. So! You, men of Slashdot, tell me what you would want to recieve for Valentine's day and help me make my geek happy."
