MUST READ! set the grid size , press space and it starts drawing :) This is a simulation and is a real concept in math rule: the red dot is the ant , the ant moves forwards once if its touching white it turns 90 degrees to the right then colours the pixel its standing on black , if touching black then it turns 90 to the left and colours the pixel white whats interesting that its thought to be a simple thing but it turns out that this will turn into a messy thing and after 11000 steps it will suddenly create a long trail that repeats (grid size must be 1 or 2) turn on turbo mode to speed up
