Wanting to take full control of his Christmas tree, Brian from Hackszine used the open-source Arduino microcontroller to drive a homemade grid array of 64 LEDs. Pretty nice. Again, a nice project that can be decontextualized, rehashed and reinterpreted in the true hacker/xmas spirit.

Here’s a cool instructable on how to turn your fridge into a Lite-Brite. I find the project to be a bit destructive as it involves painting your fridge with conductive paint, but the concept could be taken out of context and you could build it differently. Perhaps as a hangable picture frame. This is something I’ll definitely look into.
