I did my talk, and it was well received, but now I am too knackered to offer anything here but a quota photo:
Photoed by me on January 10th 2007, in other words ten years minus four days ago.
I like the contrast between the coloured lights, done with plastic bottles, and the monochrome surroundings. I remember those lights, and photoing them.
My camera back then wasn’t that good in low light. But it did okay for these photos, from which I picked the one I liked best.
