projection and optical illusion

This one is quite fantastic. I once visited the Art Institute in Chicago and in one of the exhibits was a photo exhibit, a flat black "framed" piece of art. There was nothing there but the flat black background. I said to myself, now, this is art! Today's pic happen by accident. I was enjoying a beer and
The afternoon sun was shining thru the window at just the right angle, i noticed my beer mug reflected in a blank pic frame mounted on the wall.,,. I held the beer mug into the sunlight and it reflected (projected) itself into the frame. The result was this lovely shot. -- an optical illusion.
