Benham's Disk
When the disk is spun, the colors you see are illusions. This effect was popularized in 1894 by toymaker C. E. Benham, who called his spinning disk an “artificial spectrum top."
Where: Crossroads: Getting Started
Bird in a Cage
Stare at a bird’s eye for 30 seconds, then look into the empty cage. You’ll see a ghostly bird—of a very different color—inside the cage
Lumen-Illusion
Flashing lights create the illusion of motion.
Magic Wand
Wave the wand quickly and see an image appear.
Recollections
This work addresses the poetics of motion, time and color. Participants are able to explore animated effects such as how sequences of images create movement. By displaying sequences simultaneously, movement forms are created. The history of the movement is expressed through multiple rainbow-colored images that evoke memories of legendary photographer Harold Edgerton's work.
Triple-Aye Lightstick
A sweeping glance creates images that appear and disappear in the blink of an eye. This phenomenon, called persistence of vision, is also at work in videos and movie projections, which also flash on and off rapidly.
