Evolution Wallpaper (Donate)
$0.99About Evolution Wallpaper (Donate)
The donate version of the Evolution Live Wallpaper. Includes an extended settings menu to customize your evolution wallpaper to your heart's desire. Plus, you've helped a hungry undergrad buy his next meal!
Extra features include:
* A higher framerate option. Now even faster!
* Assign Red/Green/Blue channels to different fitness measures! Measures include Touch, Battery, Time and Random (changes on touch).
* Adjust the underlying model. Customize the spawn rate, replication rate, mutation rate, and more!
The Evolution Live Wallpaper turns each pixel of your Android background into a living organism! It uses a genetic algorithm to simulate the "evolution" of these pixels (or cells), using their colour as their traits for selection.
The wallpaper starts out initially as a multi-coloured grid. Over time, this grid will slowly transform (i.e. evolve) into a single colour (or close to that colour). By interacting with your phone, you can change the optimal colour and watch as the cells eventually evolve to that colour all over again!
Here's the nitty-gritty of the algorithm (for those that are interested):
Each pixel square simulates an individual, replicating cell. Cells replicate asexually, but not perfectly (i.e. they mutate).
The cell's traits are defined by its colour -- specifically, its red, green and blue values. These traits are used to calculate each cell's "fitness" score, using an optimal colour value (see below) as reference. This fitness value determines the cell's reproduction rate, and thus its survivability in the environment.
An "optimal" colour is defined based on a variety of parameters (by default, red is defined by the amount you touch your background, green is based on local time, and green is based on your phone's current battery level).
Note: If you enjoy this wallpaper, please considering getting the donate version! Just look up "Evolution Wallpaper (Donate)" in the market.

Every time you look at it its something new,and different

Would be even more fantastic if we could assign our own relative fitness values in addition to basing them on battery etc. nice app!

Jay, thanks for this app--it is really fun to watch and think about. I just bought the donate version. Could you provide more detail on how this algorithm works? Do pixels that have high fitness form 'colonies' that expand spatially?--that seems to be the case. How often are the selection parameters updated? Thanks again.

Nice Really good app. Love Just watching them slowly be consumed by a single color. I would love to see the algorithm to really see the math and science behind this awesome app. Keep up the amazing work :-D
