Many people who spent many hours staring at the old carpet while in line for panels missed it very much and founded the Cult of the Carpet[0]. It has "priests" that wear robes with the pattern, you can buy bags and t-shirts with the pattern, etc. My favorite is the guy who painted his storm trooper armor with the pattern.
