One of my favorite optical illusionists, Brusspup, is at it again with his latest anamorphic tricks. 
I understand he shoots photos of simple oblects like those in the photo below, skews the images in Photoshop, prints them, trims the paper, and positions the skewed photos so that, from an exact viewpoint, the image looks 3-D normal. Then Brusspup starts the video camera. As the trimmed photo is rotated on the table, you see his clever 3D-2D-3D optical trickery. Brusspup generously provided high res files of the Rubik’s cube, shoe, and tape to print on 8×11″ paper, trim, and play with.  Thanks, Brusspup!
