If you’ve been keeping an eye on the ground beneath your feet, you may have noticed an explosion of pattern. It can be seen in public spaces like the Manhattan restaurant L’Amico, designed by Crème; and the Hotel Van Zandt in Austin, Tex., designed by Mark Zeff. And in private spaces, too, like the New York apartment of the actors Naomi Watts and Liev Schreiber, designed by Ashe & Leandro and featured earlier this year in Architectural Digest.
