This is an implementation of Conway's Game of Life written in JavaScript, with a Python helper on the back end for generating animated GIFs.
Draw on the grid to the left to interact with the game board state.
Click Iterate to generate the next board state. Click Run to have successive states of the game displayed automatically.
Click Generate GIF to send the current state to the back end, and an animated GIF image will be returned showing 100 successive states of the game.
