This is a picture of the blackboard at the office of my mentor, the late Ned Seeman. If we had the superpower to freeze instances of the birth of highly original ideas, I imagine we would see something like this. Looks like a Cy Twombly painting. Each one of those drawings was a milestone in the establishment DNA nanotechnology field. I had professors come to me and say that they put Ned's papers in their office just to get inspired when they were feeling a bit low. That's how original he was.
