Sometimes we think we have heard of it all, but now artists are taking graffiti, which is normally written on the sides of walls or trains, and turning them into 3 dimensional art.
This sculpture was by an artist named Kwest and it is located in Toronto.
This piece is a relief sculpture called "Rock" by an artist named Peeta.
And this one is from an artist named DAIM.
How do you think an artist takes a 2D or flat work of art and makes it 3D? What materials would you use if you were trying to create these works of art?
