Alien Lifeforms is a stylish and enthralling screen saver with an original algorithm and never-repeating appearance. It represents evolution, rise and fall, struggle for existence and for dominance between a number of colonies in a clot. (A colony is a set of cells with a same color and shape. A clot is a set of colonies that live in a bounded piece of space). You never know what colony will die or what colony will displace others till the next minute. Old cells dies, new cells borns, but there is not enought place for them all. A situation changes every second and never repeats. Only one colony can win. It is a great sight when the whole clot fills out with one colony. There are different shapes of a clot, different shapes of cells and settings for adjusting Alien Lifeforms by your taste and performance of your computer. All of these settings are described in the Help. Generally Alien Lifeforms will run on almost every computer. But if you have a fast one Alien Lifeforms will look much better. version 1.2 - backgrounds added.
