These are recent experiments by Alvin C, working with OpenGL/GLSL Bloom & Blur filters in Processing. The demos feature Alvin generating interesting complex structures from simple behaviours/rules. He writes:
This exercise experiments with a particle field where different forms may emerge as a result of interactions between particles. These forms are created by connecting particles into clusters. Each particle is aware of where and which cluster it is connected to and explicitly identifies itself through colour.
