This implementation of John Conway's game of life developed with processing language with python-mode use a random seed and mouse interaction to set seed. At any instant, the user can pause the simulation to change the state of any cell. Can too interact in the execution time.
To run the simulation is needed an installation of Processing 3.5.4 IDE and add the python-mode from the top-right menu. Once you have the Processing IDE go to the File menu, select the Open option and search for the game_of_life_sketch.pyde file. In the IDE use the run button (top-left corner) to execute the simulation.
If you need to compile this such an application from any operating system (GNU Linux, Mac OS or Windows), go to the File menu and search for the Export Application option.
