In this fascinating video, Dan Sandin demonstrates, using a triangle, square, and circle on a video screen, how video can give the illusion of subverting geometrical rules governing spatial relations. Sandin shows the three shapes existing in an impossible relation, each in front of the other, and lectures against what he calls the dangers of using "common language concepts and normal spatial relations to talk about things that are happening on the video screen." In so doing, he founds new possibilities for imagining reality.
