This is pretty cool because it feels like it is moving and shifting, like one of those eye tricks. There are a lot of different ways of looking at it, it could be anything from a snail shell to something winding downwards, two caterpillars... the interpretations are endless. Though I would suggest snipping that extra space off of the left side so the tight part of the swirl is in the center, since the flow of the picture is a little stunted from the framing and that extra bit of streaking doesn't add anything to the design.

I'm not sure how this fits into the contest, but it's very fun to look at.
