Rock'n'roll

I could spend all day watching the reflections on the canal, especially when there are a few narrowboats bringing some good colour.  I spotted this pattern alongside the moorings in Skipton.  The red blobs were moving mesmerisingly from right to left in a continuous stream, like some kind of lava lamp on speed.  I only had my small camera with me so it was tricky - with the shutter-lag - to catch the pattern.  This was the best of four or five efforts.  It said 'rock and roll' to me (though you'll have to imagine the rolling effect of the water).
