Kaleidoscopic

Any idea what this is?



I spent some time this evening at the family farm, looking at the barn.  When the sun is setting, spikes of light come through the knotholes and spaces between the boards.  Here's an idea of what it looks like.

But when I was playing with my camera, I noticed that the light seemed to read funny on the screen.  A slight sideways movement, and the spaces seemed to widen.  That gave me the idea to move the camera just a bit, horizontally, while taking a picture.  I really like the result!
