Urban Projections
We bike along with Ali Momeni and his fleet of mobile video projectors that transform public spaces into real-time sound and light shows on a massive scale. In the Workshop, John Park combines a treadmill motor and PVC pipe to build a wind generator. William Gurstelle shows us some devices that make it easy to release heavy loads, and the Maker Channel presents creations from around the country including a balloon organ, ball-fetching autonomous robot, and a lie-detector wristband.
