From a UNLV gaming historian, this surprisingly awesome gallery features tight shots of trippy casino carpets, with Vegas entrants ranging from the Wynn's Seussian threads to the Black Hole-inspired Hilton SpaceQuest, plus nationwide action like Biloxi's cowboy'd up Boomtown and St. Louis's Harrah's VIP riverboat -- covered in asterisks and psychedelic Cheerios, in reference to their VIP dining.
