Imagine having 192 little two foot trees snaking through the yard, each tree on a separate circuit and each circuit controlled by the computer.

Kids actually ran down the street trying to keep up with the fast-moving trees. These easy-to-build items are a crowd favorite and they’re also easy to store. Here’s how you build one of the trees. Keep repeating the process until you can’t stand it anymore!
