Small nice town, obviously very active in theatre and music. We were just passing by.
Amazing little museum gathering a few good optical illusions and other perception experiments. Very insightful comments in German and English.
The best one: how the brain will choose to see only one of two overlapping, inconsistent images two eyest are capturing. Likely algorithms in place similar to those used in 3D graphics to hide things behind one another. Nice comparison with Fiji islands, where natives are said to have not seen the first Western ship, too big to exist even when moored next to them. A special example of ‘turning a blind eye’.
