I'm very excited because I've just got the delivery of the prototype of a new model I've set up. I already set up a co-creator to 3D print a photo as a halftone grid but for this new one I wanted to see if I could have two photos in one model.
The photos are stored as rods of varying length, the two photos are interleaved side-by-side but the grille in front hides one of the sets of rods when you look from one side. As you move to the other side the other photo is revealed.
The photos don't really show the effect that well so I've put a video on YouTube
The model is set up in Processing so I should be able to make a co-creator soon...
