A tattoo posted by the artist on Instagram is blowing people's minds across the Internet.
Matt Pehrson of Zion Tattoo Company in Utah, shared a photo of a tattoo he did on the back of a man's head that is a stunning optical illusion.
Matt tattooed a series of thick black lines in a manner that it appears the man, Ryan, has a giant gaping hole in the back of his head.
"Did a crazy thing on my friend Ryan today... We have a lot left to finish on his dome. What do you all think of a piece like this?"
Despite the photo being originally posted back in April, it just recently started making waves.
Here's his Instagram if you want to see more of his work.
