3D Illusion Sketchbook Drawings by Nagai Hideyuki

Playing with light, shadow, and perspective, Japanese artist Nagai Hideyuki creates these stylized optical illusions using the entire spread of his sketchbooks. Once propped against a wall and viewed from the perfect angle his illustrations seem to leap off the page creating a visual effect similar to an MC Escher drawing. See many more examples on his website, Facebook, and deviantART. (via visual news)
