"Conway's LIVE Wallpaper" for Android
One of my old college friends asked
if I wanted to write a live wallpaper app for the Android OS "for fun".
Of course the first thing that came to mind was to use Conway's Game of
Life to generate beautiful patterns! While close inspection showed that
the Android App Store had about a dozen Conway live wallpaper apps
already, they were all rather bland to look at. So, I wrote what I
consider to be the prettiest of them all by far. ^_^ Dragging your
finger accross the home screen of your phone leaves a trail of "living"
cells that move, grow, and interact with each other. You can also
change their shape, color patterns, and the ruleset that governs how
they propagate, as well as the speed of the simulation.
For those unfamiliar with it,
Conway's Game of Life is an artificial life simulation. Each
single-celled critter lives or dies based on a custom set of rules.
Each rule models a behaviour, like two neighboring cells giving birth
to a new cell, or a cell surrounded by too many others dieing from
overcrowding. The simulation rules can create beautiful patterns, and
tweaking the rules - Which the premium version allows you to do! - can cause even
more elaborate patterns to emerge.
