This simulation was designed as a final for contemporary mathematics and was designed to try and simulate how bacteria naturally grow. Bacteria tend to grow in circular colonies, which in return appear to be like fractals. The bacteria in this simulation are generated using javascript pseudo-random Math.random function. Bacteria also always grow exponentially. As for each bacteria that grows, that same bacteria will then reproduce. Meaning that the reproduction rate is around 100%. Please note that there are a few bugs with this simulation, one being sometimes the bacteria overlap each other, and the other being that because of the array size and how they rapidly they reproduce the allocated memory tends to be completely taken up. If your FPS on the left drops below 10 it's best to refresh to get a new structure. Below is a hot map of actual bacteria and their formation and I also included a formation that I found.
