This is really cool, it looks like it's pretty easy to get started with Shadertoy and your guidance.

One nitpick: in section 2.1.1 on implementing the reactions, you refer to "simulating the reaction A + 2B -> C"; should this have "4C"?

The section you're referring to is meant to first give the update rule for the general-case of a reaction that is not autocatalytic.

I'm not sure what made you think it should have 4C, but if you want to explain me the reasoning that led you to this conclusion, I'd be glad to fix the article and make it clearer

The equation in that section for updating the concentration of C has a "4 * speed(t,x,y)" term, it seems like that should correspond to 4C in the reaction, especially because the equation for B has "-2 * speed(t,x,y)".

EDIT: Also, the text after the equations says "Notice that the numbers in front of speed(t) come from the quantities in the equation that summarizes the reaction."

You're right, how did I miss this ?! Thanks for picking this up
