Have you checked out The New Yorker, and specifically The Talk of The Town? You're in for a treat because the 4/5/10 issue titled At The Casino FLOORSCAPES by Lauren Collins discusses carpet and more specifically 'psychedelic' Casino carpet as interpreted by New York-based photographer named Chris Maluszynski.
In addition to the article, there's a companion Slide Show: The Carpets of Vegas published on March 29, 2010 which offers a glimpse of 8 bold, kaleidescopic patterned casino carpet floorscapes. I suggest you look through them first then return to Lauren's article.
Collins quotes Christine B. Whittemore, who runs a blog called Carpetology: “A lot of the busyness of the patterns may be about keeping people active, as too much relaxing may not inspire gambling.”Talk about excited!
