Don't Fall In!
This illusion tattoo makes you think this person has a weird hole in their arm. This would honestly trip anyone out, especially to have it on your arm. Super neat, still!

What a wild idea for a back piece! Conveying perspective like this is really difficult. It's probably even crazier when this guy is walking or moving his body... It probably looks like the person in the tattoo is actually moving around.
