Aliens (or we can call them space invaders) are generated on the random basis initialized with one seed number.
I was quite surprised that my algorithm creates some very interesting (and unusual) forms of space invaders.
What about a purpose? Just for a fun. Or maybe if you are into art you can use it as a background for
you own designs. Moreover you can give a name to unnamed aliens. If you have some time and ideas, please do it.
