Impossible anaglyphs; about things one can see but that doesn't exist. Anaglyph images are made up of two color layers, superimposed, to produce a stereoscopic 3D effect, when viewed with 2 color glasses (each lens a chromatically opposite color, usually red and cyan). In the brain the visual cortex joins the image it receives from each eye into a perception of a three dimensional composition.

He was involved in publishing educational magazines for children and wrote many books on various scientific topics. In 2008 he received the NWO Eureka Reward.
