A demo of the power lookup in 2D. An ICE particle grid is the perfect way to experiment with texture warp and lookup maths.

Another distributions test, this time iteratively growing a colony of points over surfaces
It’s hard to beat the look of evenly packed points.

I hesitate to call this a power lookup, for want of a better name

I made an ICE node for generating 3d cell noise. ( .. generating the 1st closest neighbour distance function)
