Things look oddly colorless in this room because they’re lit by light of only one color—a sodium vapor lamp of the type often used for streetlights.
Where: Bechtel Gallery 3: Seeing & Reflections
Created by artist Bob Miller, this classic Exploratorium exhibit is a “live” painting that uses light from the Sun as its palette.
At this exhibit, an infrared camera detects the heat radiating from warm objects and projects it on a big screen, allowing you to see what’s hot (and not) about you and the other people and objects in your surroundings.
