"We have a downstairs room in need of help," Janet Humphreys writes in an e-mail. "It has two challenges: It is oddly shaped, and it is my teenage son's primary hangout. ... He wants it to be a cool multimedia room that will accommodate his friends' interests in computer games, video console games and music. I want to be able to use it after he's gone, which is September 2009. Can you help us?"
