(yet fun) ideas...
Turn signal jackets (my personal favorite)
Darth Vader Cupcakes
A totally geeky NES controller coffee table that actually works (not for the faint of heart!)
A pumpkin carved in code
An uber nerdy clock
DIY Tetris magnets
Your very own bat lamp
Or perhaps an old phone-inspired iphone case.
Craft nerds eat your heart out!
