Reaction-Diffusion Advanced

And now for something completely different... ;-)

After implementing a sharpen shader for Tooll3 recently, today I wanted to extend it a bit, so I can drive the SampleRadius parameter with a texture, since this is what defines the size of the tendrils when used for a Reaction-Diffusion setup.
It worked on first try and this video is showing the result with an animated ShardNoise driving the SampleRadius.

I combined three more ShardNoises into a vector noise that displaces the RD loop - for that I also wrote a very simple texture remapping node, to be able to remap 0 - 1 textures to -1 - 1 so they are signed and displace in all directions.

Fun :-)
