When Doves Fry
A Zoetrope with Fire!
A Zoetrope is a mechanical means of achieving the illusion of motion, aka animation. This one works by having two counter-rotating cylinders, the inner of which has slits to act as a flash, and the outer of which has animation frames. Inside is a ball of fire.
The animation is of a dove flying. This zoetrope was mounted on the All-Terrain Tiki Bar for Burning Man. A stand-alone version was shown at the following Decompression, where I was placed next to the Flaming Lotus Girls piece (seen in the background below).
