My son found the Incredibots site months ago, and showed me, and I made a few cars and stuff and though oh how interesting and then let it drop. But there are now any number of wonderful machines built there… today’s is the pendulum clock. Now (assuming I have it right) the mechanism isn’t correct – it’s backwards – but even so it is a wonderful thing to build. Some people clearly have imagination. The Panzer IV is pretty good too.
