Hi Ben,
Love your show and what you do with game consoles and pads.
Today I notice this Kickstarter projet: "Omni - Move Naturally in Your Favorite Game" so I thougth... "Great, my favorite game is Fallout on my PS3! 
" but when I look at the botoom of the page...
FAQ: Does the Omni work with consoles such as XBOX and PlayStation?
No console support has been announced at this time.
That really upset me 
, but then I realize that the Omni systen it's all about mapping the movements to key strokes... and I know a guy that could do that to a game pad... Ben Heckendorn!!! 
So this is my Challenge: "Make Omni compatible with PS3 or/and XBOX"
In order to do it I thought, a Raspberry Pi could handle the Kinnect skeleton recognition and interface the sisthaxis game pad.
Could be this your Ultimate Challenge?
