The Spectralizer

Spectral Art is a physical format, so a screen can never truly reproduce it - but you can get close. Twelve of Jumbie's pieces are lit here by a simulated Portal Frame lamp. Watch colors vanish, transform and reappear as the cycle shifts. Left and right step through the artworks; up and down change the lamp pattern - use the arrows, the keyboard, or swipe on a touchscreen. Tap the artwork to view it full screen with the lamp still running. The controls below are the frame's own, and you may also use SpectralBreak further down to run your own images through the same simulator.

Wear chroma-depth glasses for this. They refract each wavelength by a different amount, so a chroma-depth lens turns the color differences in the artwork into depth: reds pull forward, blues fall back, and a flat single-layer print separates into layers hanging in front of one another. Under a Portal lamp that is cycling, those layers move independently as each pigment brightens and recedes - which is the effect Spectral Art is built around, and the reason a screenshot never does it justice.
