Defenestration -- the art landmark building on the corner of 6th and Howard with all the furniture hanging out of the windows and crawling up the walls -- is celebrating its 13th anniversary. On March 5, 1:AM Gallery (right across the street from Defenestration) will kick off a fundraising event and solo show by the artist, Brian Goggin. Funds will be used to repair and restore the building so it will be "once again beautiful by day and vibrant by night."
On the artist's website, there's a history of the building and many opportunities to donate. You can even "sponsor" a specific piece of furniture.
