Gary Aden and his son Daniel are exhibiting a 3D Zoetrope they created over the course of a few months at this weekend's .
Composed of a series of concentric stationary Google Android dolls (Daniel is a Google employee, and the family lives in Redwood City) affixed to a disc, the zoetrope creates an optical illusion when strobe lights flash on the disc as it spins. The dolls appear to be moving, when in reality the eye is simply viewing a series of the stationary dolls which have each been constructed in a slightly different position.
The Maker Faire concludes its two-day run today and will be open from 10 a.m. to 6 p.m. at the San Mateo Event Center. For more information about the event and how to get there, click .
