vec2 st = (vUv.xy * h + time/100. + 1.); This will move it with time. The tiling is not infinite, it's inside a big triangle, so with enough time you will travel outside of it, but I guess with proper bounds you can move around or make the triangle bigger. vec2 st = (vUv.xy * h/(1.+0.5*cos(time)) + time/100. + 1.); Periodic zooming. Looks like the sphere gets dressed in a cape.
