If you've never seen this illusion before, prepare to be thoroughly baffled! It appears to be absolutely impossible. Fret not, though, because this video contains sufficient proof of its validity. This is a re-created version of Roger Shepard's "Turning the Tables" illusion.
This visual phenomenon is taken to another level by drawing it, along with a cutout that "proves" it, and providing links to the same drawing and proof cutout that you see in the video. Feel free to use these items as guides for drawing it yourself, or just print them out to see that this unbelievable illusion is actually believable!
