Electric Blue Abstract

The weather is awful outside again; damp with not enough natural light. So instead I had a play around with some macro shots at lunch time. I liked the way this one turned out. Can you guess what it is?

I'm going to York tomorrow for the weekend. I had hoped to visit The Yorkshire Sculpture Park but if the weather is going to be like this I might have to give it a miss as I don't fancy wandering around in the rain :-/
