Gary Foshee shows off the harmonic pendulum he built, and explains
how it works and what the challenges of construction were. This is
one of the more hypnotic pieces from the 2014 Gathering 4 Gardner in
Atlanta, Georgia.
Karl Schaffer designed a way to make a series of polyhedra using
string and three human bodies. Using three people, the piece is a
very simple lesson in geometry, showing how one shape can transform
into another.
