Artists have many techniques at their disposal to convey a sense of depth on a flat picture plane: layering, linear perspective, atmospheric perspective, and so on. While these are normally employed by artists making static pictorial images, Andreas Gysin and Sidi Vanetti created an abstract, generative series of animations called Wayfinder that simulates depth with intriguing simplicity.
We see dark gray forms appear out of blackness, stacking on each other in neat piles. As the layers build, the shapes get progressively smaller and brighter. This creates a gradual 3D effect, as if gray conical forms are emerging from the dark and then disappearing as they reach the picture plane. The artists refer to this effect as “2.5D.”
