Konbanwa Mineo san,

If you take a close look to the picture - the curves are all around a light
point on the boom. It seems to be an reflection of light. Could it be that
the curves are trails from this light point. We know these images from see
star trails due to an long time exposure. The gradient boom is swinging
around and "paint" such trails. 

Dewa,
Mike
