"The Hole House projects utilized the act of demolition to explore the qualities of light... We stuffed some of the holes with colored acrylic rods. We then had a big party, and demolished the building the next day."
See more of Hole Houses #1 and #2 at Hutchison & Maul Architecture. (And don't miss their building projects, too. Seems the experimentation pays off: These guys have created some really interesting built work.)
