This Optical Illusion Creates A Hole In Your Hand
This optical illusion occurs because of a process called binocular rivalry. You probably don't realize it, but your eyes sometimes vie for "dominance." If there are different, competing images seen by each eye that can't be easily combined, one image will end up suppressed by your brain. In this case, that suppression makes it look like your hand has been through a giant hole-punch!
