Untitled Light

Another fun long exposure shot, any guesses what it is?
It took a lot of effort to stop all the reflections that could initially be seen!

Hint: It is not smoke trails!

Something good: I got a piece of maths homework done for the first time in a while, in a free where I could've been having a lie-in! (Of course I should always do my maths homework, but I don't... so it's good when I actually do it!)
Something new: Hegemony (loosely described) is the power a dominant social groups holds above others in society! A good media term there for you ;)
