Mystic Rose Particles
This is one of my math-chemistry-inspired simulations. I created a particle system, and when simile particle-types collide, they join to form a 'mystic rose'. 

The mystic rose pattern is really cool. It's just a circle of dots, equally spaced apart, with lines connecting each dot to every other dot in the circle. Very simple, but it creates beautiful patterns.

In my simulation, the roses grow as they collide with more particles.
