when one square runs into another one changes color to mach the other one. eventual the squares should be all one color. there's 60 little squares. you can set their speed with the slider in the top left corner. there is six colors red, blue, green, yellow, purple, and black. each color starts with 10 squares. This is a sumulation about how people often change to fit into there environment and society they are in. The speed slider is kind of weird, but it's good enough. I recommend speed 8.
