I experimented a bit with video. The weather was perfect for it, as reported earlier.
One laptop with webcam streaming live from my balcony to ustream.tv. And my little 10fps camera on board. Then fool around until the batteries run dry.
Afterwards I found a problem in one of thumper's "legs". It limped. Exploratory surgery confirmed the great fear: a gear is missing some teeth. Oh well, we'll always have the photos.
