Build a remarkable drawing machine from 1913 adapted by Senior Apprentice Angus Macmullen and Educator Josh Revkin. Since their first adaptation, it's been revised at least 5 more times. We will teach you some ways to program it. Then you will go on to invent your own programs. The possibilities are infinite. Add color and shadows.

With modular wooden pieces, wire and rubber bands, construct a hand with fingers. The parts will work in a dozen basic configurations.

Build a project that lets you blend primary color red, blue and green leds to produce white light. Then, begin experimenting with blocking one led after another to create colored shadows to see what happens. But shadows are black aren't they? Nope, not here.

Understand Additive and Subtractive color using LED lights.
