Stir Fluid SimFree
Stir is an interactive fluid simulation. Swipe the screen to stir up vortices, and be mesmerized by the ensuing perpetual swirly motion. To slow things down, press and hold the screen to dampen the whirlpools. This is the standalone app version. There is also a live wallpaper version available. Choose from a number of presets that change the simulation behaviour and rendering style, or modify the parameters individually. The underlying physical fluid simulation is based on novel research which support the two aforementioned features. Resource consumption(CPU, memory) is relatively lightweight and should work well on a range of devices. Of course the harder you push it (a key parameter being the number and size of particles) will determine what's possible, but even modest hardware should be adequate for lower particle counts. This is a beta release. Any feedback including bug reports and development suggestions are welcome.
