@exoteric: Looks like IlluniRoom is a simple version of 'Foveated Rendering' where the point of interest is rendered fully, but peripheral areas are rendered partially or in lower resolution (I say a simple version because it's not tracking eye movements, expecting the user to concentrate on the TV screen).

May tests of foveated rendering showed users didn't notice any difference from full rendering.  I expect the IllumiRoom is something you have to try to see the full benefit.
