I reckon that idea sounds pretty good, Kyl3. Although I'd probably make it a bit bigger than 10cm.. don't think that would be enough space for the light to evenly fade out. It'd probably just end up being a thick bar of light around the TV. Probably better off checking eBay, goodguy. Ikea seem to sell 'em for about $100 for 1m, compared to about $25, with remote etc.
