The Telestereoscope is an optical device that increases the distance between your eyes. This has the effect of enhancing your perception of depth. For some people, it makes the world seem miniaturized: cars become toys, and landscapes look like model train sets. For others, the environment deepens and splits into many distinct planes. One viewer described it as "like looking at the real world through a Viewmaster."

Cassidy Curtis and Chris Whitney built the device to bring to the Burning Man Festival in the Black Rock Desert, Nevada, which took place in the summer of 2000.
