This simulation shows how diblock copolymers (chains of A-beads and B-beads) spontaneously "self-assemble" into patterns. This is driven by minimizing energy: A-beads attract A-beads (blue), B-beads attract B-beads (red), but A and B beads have a weaker, fixed attraction.
Fraction of 'A' beads per chain. Requires restart.
