I am trying to make interesting things to go in our front window, thinking about light and inputs and outputs. We're going to be working on an installation with teens later in the summer around these themes, and so I'm brainstorming for that. Trying out the light... she's standing on the big mat switch. I made this pretty fast. It's just a motor (the red lego kind), taped to the top of an overhead projector. I attached a piece of boxboard to the motor, and punched different size holes in it.
