Cyclically symmetric attractor (Patreon)

Here's a little variation on my Lorenz system tutorial. The setup is almost the same, but here I've implemented the Thomas' cyclically symmetric attractor.

Really cool system that has only one parameter - b.

I've left it as a uniform float on the GLSL TOP, try experiment with different values - I'd say the most impressive stuff comes between 0.208186 and 0.32899. 

Within this range the system stays in some sort of equilibrium.
