A Back Blip

I have just downloaded photos off my camera I hadn't realised were there along with the photo I have taken for todays blip (16/01/10). One of those photos was this photo taken at a fireworks display back in November. It caught my eye... I'm still learning with photography and in deed with fireworks I get quite frustrated, but this one I don't think I could repeat and I couldn't tell you how I got it... its fairly random! Still I thought it was worthy of a back blip
