If you look back at least weeks, if not months ago (http://dianelou-mixedmedia.blogspot.com/2010/11/new-startsand-finish.html), you'll find the start of this piece. It began with a wooden checkerboard for a background, topped by a wooden box painted black. The two pieces that are screwed to the top and bottom of the box are, I believe, from some type of Lego set that I found in the bins. The finial is an inverted pendulum piece (plastic) from a very cheap clock.
I often find cleaning or sorting or just looking through things brings out things I had forgotten I had, or things that were set aside when I just couldn't figure out where they were going. It's a great way to jump start some new art!
