The Fling mini by Ten One Design is designed to provide you with tactile control for those touchscreen games. You get a dual thumbstick-like configuration with actual thumbstick-like controls, rather than swiping your finger around virtual circles on the screen. The trouble is, as you can quite clearly see, it obscures about half of the screen.
The Fling is a suction cup D-pad joystick that fills the tactile void of iPad gaming controls. Made of a bendy siliconesque resin, aluminum and a couple of suction cups, the Fling still allows you to see the action on your screen while enhancing gameplay ten fold.
