While watching NHK, one of the major Japanese networks, they featured the architectural paper work of Eriko Horiki (http://www.eriko-horiki.com/).  Even though she's not a PM person, her work with large scale paper installations (walls, columns, tables etc) is quite impressive and beautiful.  She's taken an old, traditional art form (Washi paper making) and interpreted it contemporarily, not unlike many of us working with papier mache. Her work should serve to inspire our own muse as PM artisans.

Here is an example of one of her works, a wall of back lit, seamless paper
