http://appshopper.com/entertainment/strings It's like a screen saver pretty much and the effects looks cool. There are also a lot of options to change the effects.
so we have to open an app to get a screen saver? 1) a screen saver is only fun when you don't have to manual activate it 2) the battery life of idevices is mediocre as it is. I don't need something useless (ok, more useless than others) burning up my lithium ions. thx anyways.
