A new live wallpaper (LWP) app has been released on the Market. LWPs may be a dime a dozen, but this one is definitely worth a look:
From what I can tell, there is no actual relation to NVIDIA/Ageia's PhysX engine, other than a focus on physics (who would’ve guessed?). The effect is quite cool though - the particles move based on how you’re holding the phone, and can be set to act in various manners. Very nifty.
There are a variety of color combinations available (“Deep Blue” is below), and you can opt to change how the particles act. Still, a few more options would have been nice - for example, you can’t define the color of the background - it has to either be black (as below), or the color defined by the combination selected (for example, in Deep Blue it’s a medium blue).
The biggest drawback: like most LWPs, this thing seriously zaps performance - in fact, it firmly establishes itself in my book as the most performance-killing LWP I’ve ever used. Even after playing with it for a few minutes, menus and transitions are still extremely laggy, and apps take longer to start and run.
As with most apps, the PhysX Live Wallpaper is available through the market.
