Description

Basic drawing of "blivet" or "poiuyt" impossible object. If the bottom section is covered up, then there are two bars with rectangular cross-section descending; while if the top section is covered up, there are three cylindrical rods ascending. If both the bottom and the top are covered, then there are only six evenly-spaced parallel lines...

For version with backgrounds to enhance the illusion, see File:Poiuyt--opaque.svg (or for a monochrome version, see File:Poiuyt-pseudo-backgrounds.svg ).
