No window pop up in Mac OS X

[nimbusLiQuid]

the main function runs into the while loop, but no window pop out.

conway.py freezes under Mac OS X for me.
The problems are as described here: http://stackoverflow.com/questions/3441874/matplotlib-animation-either-freezes-after-a-few-frames-or-just-doesnt-work

I fixed it in the meantime changing time.sleep(0.1) to plt.pause(0.1).
Even better would be using the update function or GTKAgg.
PS: Thanks for the implementation!
