Here's my latest project, pirNet. It's a set of devices you put around the house that detect and displays motion. So you can tell where people are in the house or, if you mount them low, watch the pets wander from room to room. The display is abstract so it looks cool, but if you know which squares of LEDs correspond to which rooms, you can read it like a map.



Put devices in different rooms. When motion is detected in one room, it's displayed in all of the rooms.
