I spent a few months working on this project, it is horribly optimized and unbearably slow but I did it! Conway’s Game of Life contained in Desmos geometry. I don’t know if any of the geometry tools were actually necessary but it is far too late now.
To draw, drag the green point around and click the green square, click the red rectangle to erase. Run the save/load actions to save/load, and click play on the ticker to watch it go! probably click Resetsearch before pressing go though.
