Alien Lifeforms is a stylish OpenGL screensaver. It represents evolution, rise and fall, struggle for existence and for dominance between a number of colonies in a clot.
It is not yet another Conway's life clone - Alien Lifeforms uses it's own original algorythm - it is really 3d and it's patterns are never repeat.

AL was released by SoftForLife.
