A Fixture
I think one of the things that is making it appear rectangular are the ears. In the photo the ears slope away at around a 25 degree angle and in Leigh's version they are parallel to the side of the face. Honestly, I am nit picking since I think Leigh is doing a fabulous job and I am very impressed. I think the whole little project is just a terrific idea and Quang's advice makes it even more so.
