A mind-bending optical illusion

This illusion won second place in the annual competition for the Best Illusion of the Year.

As you watch it, keep in mind that this is a competition for optical illusions, NOT for sleight-of-hand or video tricks or other stage "magic."  That's a real mirror, showing the reflected cylinders and the hands of the operator.  The entire illusion is based on the neurophysiology of optics, and the human mind's interpretation of what the eye sees.

If you can't figure it out When you give up, the basis for the illusion is explained in this video.


  1. Excellent!


  2. Makes you wonder about how much we think we see is what we actually see. Consider those times you've seen the moon looking huge near the horizon...it wasn't.
