Microsoft have created a 3D web browser that can project images onto every wall of your room and even account for you furniture.
The SurroundWeb project can render "immersive multi-display web rooms" at greater than 30 frames per second with up to 25 screens and up to a 1440x720 display.

It is the next evolution of Microsoft Research's 'IllumiRoom' which basically did the same thing but with gaming (see video below).
To achieve the same effect with a web browser marks a big technological leap as games a re much more predictable than the internet.
If you want it you'll probably have a fair wait on your hands as the project is in its early developmental stages - but it's an exciting glimpse into the possible future of your living room.
