Another "impossible object" along the lines of the better known "impossible triangle" and "impossible cube".
Some of these "impossible objects" can be made, but the actual object only looks impossible from one viewpoint, which is the camera's viewpoint in this case. The actual object bears little resemblance to the "impossible object". If one Google's "impossible triangle" or "impossible cube", one can find real photographs of these impossible objects as well as alternate views showing how the object was built. One can probably find an Ames room too.
M. C. Escher was a master at drawing impossible objects. On my walls, I have four of the prints from this
site but the waterfall is my favorite. I ask people "what's wrong with this picture?" Some get it, some don't. But if you could build it, you would put Exxon out of business in a day!
