French street artist Astro’s recent work in Loures, Portugal has been gathering a lot of attention because he used an optical illusion to make it look like there in a tunnel running through the building. The mural he painted is massive as it covers an entire side wall of a six story building but while looking at it, it’s kind of hard to imagine it’s a flat wall on a building
Aside from this mural he has loads of other art that makes use of optical illusions (i.e. mind-fucks). Check out some of this work below and be sure look at more of his amazing work.
