iControlPad 2. With just under two weeks to go, the project has met over half of its $150k funding goal.
Improving on the original iControlPad, the device includes a QWERTY keypad as well as a swivel-mount that clamps to your smartphone of choice. As demonstrated in the video above, the controller is expected to work with any app due to its open-source nature. The Kickstarter page for the iControlPad 2 lists Ouya and Raspberry Pi support in addition to a 12-14 hour battery life.
