Any ideas?

My contribution to Abstract Thursday (thanks Ingeborg). Any ideas what it was before I artyfartyfied it?

The shark attack in Australia has unsettled me today. Don't get me wrong, I think it's horrific and I feel so, so sorry for the man who died and his loved ones... but I'm also worried about what the search for the shark entails. I'm guessing the plan is to kill it but how will they know they have the right one? How many will be killed in the process? I've loved and been fascinated by sharks my entire life... the repercussions of this attack just troubles me.
