SaverTooth scaffold clamp by Dave Holinaty and Joshua Schultz. The plywood looks a bit wobbly being cut by the circular saw at 0:20, and I'm not certain that this is a great way to secure sheet goods for cutting. Nevertheless, a clamp that secures to scaffolding could be a very useful tool, and this may be a much better alternative than the current methods used to work on materials while up on scaffolding. Failed on Kickstarter, with $0 funding.

A bit of a stretch at $200, but still interesting.
