When it comes to graffiti, long gone are the days of 2D art. The world has brought you guerilla knitting (check out Knit The City), and now there's even cross stitch street art.
If we take it back to the traditional spray can art though, you'd still expect 2-dimensional. Not so when you check out these awesome street artists.
Mixing illusion art together with street art they have changed the way graffiti looks to the viewer with their art really jumping off the walls.
