Magical Mirror Anamorphoses
“With mirror anamorphosis, a conical or cylindrical mirror is placed on the drawing or painting to transform a flat distorted image into a three dimensional picture that can be viewed from many angles. The deformed image is painted on a plane surface surrounding the mirror. By looking uniquely into the mirror, the image appears undeformed,” notes from Wikipedia. In this news post, you can see the incredible anamorphic etchings of Istvan Orosz.
