ENEKO ALONSO  This is my first application ever in XCode. First it was only 10.5, due to some new objects I used. On this version I removed those components and tried to compile it for 10.4, but apparently I missed something.

I'll try to find what it is :)   
(Version 1.0.3)

ENEKO ALONSO  I know! It's a pain it requires Leopard.

This is because it uses the new components from XCode 3.0 for the toolbar.

I have pending to develop a version without this requirement, hopefully I'll have it soon.  
(Version 1.0.2)

ENEKO ALONSO  My Game of Life is a cellular automation "game". Although it is called a game, it is a zero player game, so the only thing the user can do is watch the evolution of the cells, besides modifying some cells and creating some structures.

There is more info about the history of this game and its rules at Wikipedia:

Thanks for the interest for downloading this tool (my first Mac application :)
