Description

This looks like a terrific project, but I'm confused. If setting output to graphical doesn't yield a valid return type, but simulation state needs to be retained and updated between rounds, how would GPU.js handle that. Surely for that kind of application, don't you need an updated array and graphical output? Any pointers would be awesome. Thanks in advance.

Research direction
The issue asks how to build Conway's Game of Life using GPU.js. The contributor should first review GPU.js's documentation on how to return arrays from kernels and how to pass data between kernel calls. Look at existing examples in the repository, such as the 'kernel output' examples. The Game of Life requires updating a state array and optionally rendering it; the contributor can investigate using two kernel functions: one for updating the grid and another for rendering. The key is to understand that GPU.js kernels can return arrays, and the state can be passed back into the next kernel call.
