Don't look directly at the picture, what you want to do (for beginners) is place your nose on the picture and pull back about 8 to 10 inches, trying to look beyond the picture, you'll start to see the outlines of the blocks, when this happens, you'll begin to see the 3D-ishness of the picture... then you'll see Link with his shield in NES style, the blocks are 3D and the empty space is behind him.
