This project is yet another node in my home’s sensor network.  It needed two main functional parts: (1) a motion sensor across the entryway to my bedroom, and (2) a switch to control the lights on my bed (my canopy bed has lots of little LEDs hanging on it).  It would communicate wirelessly with the rest of my sensor network and also allow my computer to control the bed lights.  Since it would be fairly visible, I wanted it to look pretty.  My bedroom kind of has a fairy-tale theme to it.  With a starry fairy-tale princess bed, a mushroom table, a hat vine, and dragonflies on the wall behind my bed, I decided that this sensor node should evoke the feel of a forest pond or stream.  A while ago, one of my art teachers gave me a bunch of slate because she was curious what I would do with it (thanks Dr. Ushenko!), and I decided it would be perfect for this piece.
