We got a whole bunch of new office chairs at work and they came in these strong sturdy boxes, so I got the idea to take a few of them and (using McGroovy's Box Rivets) construct a play house for Tesla. It's not really done yet but she's still pleased with it. Over time I'll add some more interior decoration, a doorbell and a light she can turn on and off. I'm also thinking of inserting her OLPC laptop in a way that it functions as a TV. I could maybe write some code that based on motion sensing (it has a built in camera) it could start playing her favorite youtube videos. I bought some knobs (for doors and windows) at the hardware store but they don't quite work because the screws that come with them are made for attaching to thicker material so I still have that to work out as well. I painted the exteriors white with spray paint, but I should have just used a brush. Still, it works more or less and looks ok. I added some touches with glue and construction paper and I'll add more over time.
