And I thought I was the only person who waits in the car parks of doctors and hospitals - although I try not to stray in incase they try to hold me there as a medical curiosity! Very entertained by this though, sometimes the simplest picture can make for something quite incredible - the colours are quite amazing and we could easily be looking at a Satellite image of an oil spill making it's way through a large river.
I think somehow that's how it happens. One little drop or barge full at a time. It kept me entertained for a few minutes. :)
