Kaleidoscope is very playful and educational at the same time. Here you can play with and learn everything about color. Kaleidoscope functions as a very large and completely walkable lightbox. On its surface float in separate layers inks in cyan, magenta and yellow (CMY). But these colors what we see are not there, they do not exist outside of our head, they are completely created by our brain and so definitely "virtual". Every kind of pressure – be it with one finger, with the feet or be it with the entire body – displaces and shifts the inks and it produced by overlapping the "real" colors red, green and blue (RGB), which can be picked up and recorded by human retina.
