Fibrous Automata : An Interactive Diffusion-Reaction Shader

Hi everyone!

I just wanted to share this art piece I made for my senior project at university:

I’m using a Gray-Scott Diffusion-Reaction algorithm from Karl Sim’s website: http://www.karlsims.com/rd.html
and LEAP Motion to get the hand tracking. I built the controller with an Arduino (Thank you UE4Duino! https://forums.unrealengine.com/showthread.php?68643-UE4Duino-Arduino-to-UE4-plugin-Release!)
It’s just one plane with a material, and I’m doing the multi-pass through Render Targets. The temporal AA really gave it an interesting look. UE4Art!

Here are some more screen grabs (sorry for the low-res!) :

Thanks for stopping by!
