Looking at PIXEL through diffraction glasses with the two front panels removed (for full LED brightness) produces a very neat effect.
Diffraction glasses split and diffract light into several beams traveling in different directions. This effect will make any light source appear colorful as if it were a rainbow, similar to a kaleidoscope. These glasses have been called firework glasses, prism glasses, rainbow glasses, diffraction glasses, 3d glasses, and rave glasses to name a few. They are best used in places with lots of lights, such as fireworks, nightclubs, and light shows.
We’ve tested PIXEL with diffraction glasses from GLOFX.
