If you'd like your keyboard-packing Android phone to look just a little bit more like an old-fashioned game boy. Clip your Game Gripper onto the keyboard of your Motorola Droid, BackFlip, or LG Ally. The attachment functions as a full gamepad.
In fact, the buttons on the gripper correspond with buttons on your keyboard, which means you can map the proper buttons to functions in-game to create your own personal controller. Versions of the gripper that support the Nokia N900 and Devour are also being worked on. The Game Gripper costs $14.99. Additional buttons are extra.
