Retroformer is a work in development that should be available multi-platform in the near future, meaning Web/PC/Mac/iOS/Android/OUYA. Development was first begun on the web side of things.
The game is a puzzle based game and it's main point of attraction is the ability to create your own maps with any image editor or by using the built-in level editor. Pretty neat.
According to the website, Retroformer has been in Alpha since June 2012 and they intend to enter beta in February 2013. That's a pretty long alpha test so I'm not sure how reliable that February date will end up being. Don't bank on this being available for the OUYA launch, but we'll keep our fingers crossed.
