A macro shot of a Sea Urchin shell I bought on Ebay for a couple of pounds...
I'm extremely pleased with the way this shot has come up - it's exactly what I envisaged as soon as I saw the shell! Unfortunately, it will be one of the last macro shots I do for a while, as the zoom/focus ring on my macro lens locked solid while I was using it today.
