Gliphica

Instructions:

left click to move around the world

scroll wheel to zoom in and out

right click to spawn in points

left click on points to destroy them

(Keep in mind there must always be at least three points in the realm)

Heres a world where when a step is taken, all points get mirrored across the line from the two closest points. You'll quickly notice that if you put down only 3 points, the image will slowly expand into an exulateral triangle. Have FUN!
