The Game Of Life on Android Smartphones

[Simonmarky]

Hello, I'm new here but I wanted to share my applications with you.
I made a few months ago, three Android applications about The game Of Life, Langton's Ant, and Generations.
You can discover them here : https://market.android.com/developer?pub=Firefly
There is a creation section, where you could submit patterns (to me, in order to add them on updates) and also rate for the best patterns.

If you have any questions or things to add on the application, i'm here.
I hope you'll enjoy

Hi,
I am going to create a variation on the game for iOS. Can you tell what license is the game under? Can I just create a variation without any problem? Or do I need to add some sort of notice?
Thanks,
Fastas
