Questionable Hotel Rug Patterns

Tina over at Swiss Miss (great blog, by the way) recently stayed at the Marriot in Atlanta and noticed a rather bizarre collection of wildly varying rug patterns throughout the building. She posted a small flickr set of her findings, which remind me of that scene in Fear and Loathing in Las Vegas when the obnoxious patterns of the hotel carpet come alive in Hunter Thompson’s head, and ooze up the walls and onto the ceiling.

Why do hotels traditionally lay the loudest carpeting? Is it so it appears cleaner without actually, you know, being cleaned? Surely the designs aren’t selected based on any sort of aesthetic qualities. What’s the deal?
