I recently stumbled upon this nifty optical filter, called the Tvbeeboo. This device suction-cups onto the front of TVs or monitors up to 23″, and difuses the images in such a way to turn your old TV or monitor into a really cool ambient lighting source.
The Tvbeeboo retails for just $40 EUR (appx. $51 USD). I haven’t been able to find a US distributor, but European retailer, Singulier.com sells them and offers shipping to the US.
