A group of Parsons graduate students are responsible for Design-a-Room, an interactive tool that lets you play around with motifs and furniture items from the Cooper-Hewitt's own collection of historic design objects. The Craftsman era collection is not so big, but there are some neat standouts - a Charles Rennie Mackintosh cardtable, a Bradley & Hubbard slag-glass shade lamp, a Voysey (identified as Vaysey on the site) sideboard designed for Morris' Kelmscott Chaucer. Unfortunately, the site is riddled with spelling errors and incorrect dates, but it's a fun little toy anyway.
