Obsessing over wall coverings

I have a passion for office supplies and the apple of my office supply eye fetish is the white board. I've got one in my bedroom, but I have a problem, it's not big enough. What I really covet is a white board wall.

You've seen them in all the Internet tech offices. An entire wall covered in whiteboard material that I can draw, color, take notes on. My current whiteboard has my notes for the "Enlightenment by driving in LA" series. It's jam packed, and I need more space to note all the other things I have in my brain at the moment. Clean out the psychic RAM so I can use the space to run programs on. So yeah, I'm coveting this. Maybe I'll just go out to the office supply store this afternoon.
