This artist creates geometric overlays, that when placed on top of each other create different images.

Several different images can be encoded in the overlays, and revealed with different stacking and rotations.

Its so amazing that its difficult to believe its real.

Crikey! That shouldn't be possible.

Not only is its possible, it's what is to be expected in a carefully calculated combination of images in a colour system  (additive or subtractive).

Well, I suppose its slightly less impressive than a cathode ray in an old television scanning 500 lines of phosphor dots, fifty times a second, to create the impression of moving pictures.

However, its pretty cool and I like the way the result is analogue with the light boxes. 

It's super cool. It's just easily explained. As is the CRT linked to visual psychology.
