Arduino seems like a great way to create interactive devices but historically it hasn’t been too hot for creating the ultimate in interactivity, computer gaming. That changed with the release of the Gameduino, a version of the open-source Arduino board pre-loaded with games, sprites, and inputs for various game controllers.
The Gameduino is an open source project and the creator has build a Kickstarter page to fund the actual production of the device.
You can also DIY and grab the plans here and the board sits on top of the Arduino microcontroller. The Kickstarter version will cost $53 if it gets funded so head over there and pick one up and help support open computing.
