Felicitous Error

I had set my camera to its highest available ISO the other night, thinking I was going to try to photograph in a darkened room. I didn't. But I forget to set the ISO to something more normal.

So when I took the picture above, the 1600 ISO shot in normal daylight resulted in something I hadn't seen in quite a while: grain. Grain looks different from typical pixels. And I actually think THIS grain is beautiful. Have a look at the big version, which I've made bigger-than-usual.
