Here you see what looks like a pile of junk — a wheelbarrow, an overturned chair, the head of a sculpture, a couch and more.
But view it from a different angle and you'll see a man's face.
The work is an installation of Ferdinand Cheval, a postman who built a sculpture of "the ideal palace" in Hauterives, France.
Watch how the installation morphs from looking like garbage to the image of Cheval:
The installation was on display from April until June 29.
According to the website for Cheval's castle, Pras and Cheval have a lot in common with their work in that they both collected items they found in their daily life to incorporate into art.
"From these accumulations, it creates incredible [anamorphic] portraits," the website said of Pras' work.
The artist also recently gained recognition for inspiring some of the illusions in the band OK, Go's new single "The Writing's on the Wall."
Watch the music video, which includes Pras-esque illusions.
