This document provides an overview of the Gainer physical computing workshop which will take place on January 18th and 19th. The workshop consists of two sessions, the first focusing on an introduction to Gainer and the second combining Gainer with ActionScript 3 and the Funnel programming environment. Physical computing allows connecting physical objects like sensors and motors to computers to create interactive installations. Workshops are led by Tom Igoe who pioneered the field of physical computing and authored books on the topic.
