3D Pencil Drawings

If you liked the 3D street paintings by Leon Keer, you’ll love the work of Japanese artist Nagai Hideyuki. Using notepads as a canvas and pencil and charcoal as drawing tools, Hideyuki creates playful 3D optical illusions which must be viewed from a certain angle in order to achieve the full effect.
