One of the host hotels for Dragon Con in Atlanta is the Marriott Marquis, which until several years ago had a very iconic carpet that has been since been replaced with something boring.
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.
If you'd like to join the "Cult of Marriott Carpet", here's a handy link with tilable patterns (1, 4 (2x2), 9 (3x3), 16 (4x4), 25 (5x5), 36 (6x6) premade), reference photos, and fabric sample tests of the pattern on 4 fabrics for costumes (Cotton Poplin, Basic Cotton, Silk Crepe de Chine, Organic Cotton Sateen)
