This is actually five identical shots stacked in order to minimise noise. Funny really,
because in the end I decided to add some virtual grain. Then again, film grain can be
very effective, perhaps because it more closely mimics noise in the human visual
system. Digital noise, on the other hand, is a pain.

I missed out on the last two challenges because I was on holiday (vacation). I'm
going to Washington for work on Mon, so I thought I better contribute something quickly!
