The end of the post links to two jsfiddles:

> If you want to try out SmoothLife yourself in your browser, I made a few jsFiddles which illustrate the basic principle. Here is a Fourier based implementation that follows the discussion in this article pretty closely: http://jsfiddle.net/mikola/aj2vq/

> I also made a second WebGL/GPU based implementation that uses a discretization similar to that proposed in Rafler’s original paper: http://jsfiddle.net/mikola/2jenR/

The jsfiddles seem to still be alive, but the "Run" button doesn't work for me. Anyone have any luck with them?
