Mine looks exactly the same because I clean it. I work paperfree anyway, since I can do engineering on the PC. I ruthlessly move everything out of my visual periphery and in a storage or a cabinet away from my eyeline.

Whether that makes me a deadened robot, or even marginally more effective than the next guy, is of course not entirely clear. It's just a compulsion. But the point is that people who are fastidiously tidy with their workdesks aren't mythical unicorns, but everyday people.
