Are there any games that make use of 2 on-screen joysticks?

[GAMESHARQ]

I have a Fling Game Controller that sticks to the iPad screen and acts as a joystick over the on-screen joystick.

So far, the only games I've played have just one on-screen joystick, so they only require 1 Fling controller.

Are there any games that have two on-screen joysticks so that I could use 2 Fling controllers at once?

And some 40 more apps that use the same control that man vs machine uses.
