Spanish street artist Suso33 is currently in Madrid for the first edition of the Muros Tabacalera Street Art Festival. Dude just put the finishing touches on his latest mural, and the completed product is an optical illusion of sorts.

Composed of hundreds of abstract human silhouettes, the mural depicts five rows of shadowy figures across a white canvas. Like his previous murals, however, the miniature figures actually form a larger picture. Between each row, the artist has painted vertical clusters to create the illusion of a brick wall. Hit the thumbs to see the rest of the photos.
