I was pretty excited about the blackboard project back in the day. The plan was to go around to various offices at my place of employment at the time and photograph the state of the blackboards I encountered on my walks. Conceptually, it sounded solid, at least in my head, but in practice, most of the blackboards I discovered were rather boring. No evidence of any Einsteins at work. No graffiti or dirty sketches. And it turns out that most folks erase before they go home for the evening. Nothing like starting the next day with a clean slate, to coin a phrase. I did end up using this particular image as part of a composite, so all's well that ends well, I reckon.
