Small Measures: Chalkboard bathroom

The weekend series returns with a great idea from Beastie Boy Mike D:

Chalkboard paint in a powder room.  Makes me think of the designer's bathroom--was it Albert Hadley?--where guests were encouraged to trace their hands on the wall and leave messages in sharpie (only a little less permanent).  Or maybe it has more to do with public bathroom graffiti?  Either way, really, really fun.
