Liam McNamara builds kinetic sculpture, junk art, and music making
machines. In 2005 Liam assembled a group of 20+ artists to build the
Clockworks Installation at Burning Man Festival. Liam will talk about
how the group collaboratively designed and built the wooden clockwork
using gigantic plywood gears with, wood peg pinions, and 5 bell wood
peg programmable bells all powered by a gravity escapement, a wind
motor made of woks and monkeys turning cranks. Why we love hacking
obsolete technology how it all worked and how/why all of this was
burnt to nothingness at the end of the event.
