At most concerts, audience interaction is usually limited to cheering and listening. Here at Maker Faire, we get to see the crowd involved much, much more. The KaLEDoscope, designed by Grant Davis, is a mixture of a kaleidoscope and a camera that gets projected on the massive screen behind the stage.

It is really fun to see people walk up inquisitively, poke their head inside the illuminated box, then appear on the big screen.
