There's already like 20 of these on the market, so I figured we'd give it a pass... then someone pointed out most of those are just looping videos. We can do better than that!
So here it is! Flames is a reasonably complex particle system that gives you control over flame density, start and end color, and more. The default is just a black background, but you can select from a few built in ones or select your own custom image.
In addition, you can have the color of the flames change based on which home screen you're on. You can see this in the video, with the flames turning blue on the far left and deep orange on the far right.
The motion and feel of this one turned out nicely, though it took a few tries to get a fiery feel to it. The framerate sits in the mid thirties on my Incredible, so should do well on more or less any handset out there. Hope folks like it!
