Batteries

I was playing with my flashgun (not a euphamism) in the wee small hours of the morning before going to bed and took a load of pictures of batteries and the inside my bathroom cabinet and under the bed and stuff and basically came up with a load of rubbish, and then promptly forgot about them. Hovever, on re-reviewing them a week or so later, I've realised that this one ain't so bad, so I've decided to backload it anyway.

It's batteries.
