> A pseudoscope is an optical instrument made with two prisms. As seen in the drawing, the mirrors reverse the image in each eye causing some items viewed through it to look quite unusual: convex objects become concave, things pointing towards you may look like they are pointing away and vice versa.

- mannykannot 8y agoIf I am not mistaken, this homemade pseudoscope works on a slightly different principle - it switches the perspective from which each eye sees the object, without any left-right reversal. The two-prism device appears to preserve the perspective of each eye but does a left-right reversal of the images on each retina (I confirmed the non- left-right reversal in the mirror case with a pair of hand-held mirrors.) https://en.wikipedia.org/wiki/Pseudoscope#/media/File:Pseudoscope_prism.png https://en.wikipedia.org/wiki/Pseudoscope#/media/File:Pseudo...
