The Standard Grill in The Standard Hotel New York has a distinct flooring system, as it is covered in coins. The floor is literally tiled in thousands of copper pennies, adding a unique vibe to the place.
I don't think having a floor covered in coins is very hygienic for a restaurant, but it certainly looks cool! I wonder how much it cost?
Implications - Consumers are always interested in seeing the familiar used in extraordinary ways -- in this case, everyday pennies being used as floor tiles. Consumers already have an established relationship with these objects and thus, when objects are used in a peculiar way, they have a built-in affinity for the publicity stunt and are much more receptive.
