Surreal Fish
This is how you do a leg tattoo. The fish looks pretty normal (but still really interesting and unique) when the client is crouching, but it's a totally jumbled piece of work when they stand up. Tattoos do not have to make sense, and this one sure doesn't... That's what makes it so unique.
I See You
This artist was able to accurately convey the illusion in both positions of the arm. A lot of people find octopi unsettling, but this one surely takes the cake. After all, it has way too many eyes for comfort!
