This app simulates a simple reaction-diffusion system, where two virtual chemicals interact to create dynamic patterns. Similar systems were proposed by Alan Turing in 1952 as a mechanism for pattern formation in plants and animals. This reaction-diffusion system is particularly sensitive to two parameters: K (varies along x-axis) and F (varies along y-axis). You can interactively explore regions of K,F parameter space by zooming and panning across the screen. More info about ways to control these systems can be found on Karl Sims' Webpage. Written by Amanda Ghassaei.

Instructions: Zoom/scroll and pan to adjust the window of K,F parameter space you want to explore. Touch/drag to interact directly with the system. Press "v" to record a video.
