I did something similar a few years back(press 'q' to see the individual particles move): https://lorentz.app/experiments.html https://lorentz.app/experiments.html It's much simpler in design though. Each particle has a constant forward speed, and varying move-angle. For each step, it can either change it's turn-angle to be more left, or more right. The turn angle then determines how strong the 'glow' of a particle is. If it turns strongly to the left, the glow is strongly red. Vise versa for blue and right. Then, for the upcoming iteration, the underlying point of the particle is evaluated by colour. If the colour the particle is under is red -> become more red. If it's blue -> become more blue. So this way, it's a dynamically shifting system where particles turn from blue to red depending on it's surroundings. All calculations are made on the GPU. The positions are encoded into textures (last 3 positions to calculate current moving angle), then also the previous step's render. Often particles becomes very isolated due to it's high turn, there are clusters. But then a huge pack of opposite-turners may come and disrupt this. Sometimes one colour wins.
