Aurora
A reflector stretches light from colored tiles into long bright ribbons.
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
Colored Shadows
Step in front of this wall, and you’ll make shadows of various colors—yellow, magenta, cyan, red, green, blue, and yes, even black—that wiggle, jump, and dance along with you.
Distilled Light
Split light apart and put it back together again.
