Particle simulator

This page simulates an exponential tug-of-war between two types of dots: particles and absorbers.

• Blue dots (“particles”) fly straight and bounce off the wall.
• Two blue dots that collide create a third.
• Red dots (“absorbers”) destroy any particle they touch.
• Every particle an absorber eats becomes another absorber.
• An absorber that goes too long without a meal starves.
• The simulation stops once the disc is full; the count does not.
