This is an animated version of my earlier composition "Xenobiology 1"

You can see the drawing continuously evolve and animate.
When you find a shape you fancy, you can save a screenshot.
There are literally infinite variations.

Controls:
Click mouse to pause/unpause animation
Press + or - to speed up or slow down animation
Press R to reset to the initial frame
Press F to flip the direction of animation
Press S to save a capture (the seed value is added to the filename)

The feature value "generation" represents the starting random state which can be between 0 and 32000.
Each animation frame changes that by 1/30 (slowest) to 1 (fastest).
