A time lapse of a bunch of teens building themselves a traction trebuchet. (my test case for can a group of people that never saw one before build and fire in under 8 hours)
The audition tape that got us on Scrapheap Challenge - The second half could have been part of "Secret Life of Machines", tho we hadn't seen their take on it when we made it.
The usual clip reel. Includes a bunch of my machines in action.
