Writings on the glass wall were made visible as the shadows on the hallway wall across. I saw this when I was making my "round" at the Broad Institute in the evening. The light from the sunset made me see these writings. Otherwise I may not have noticed them. They were written from inside the office, which meant I could only see them in reverse from the hallway where I was walking. The sunset was strong, and giving me an opportunity to actually see what was on the glass wall.
One thing you need to know about Broad, almost all the office has glass walls. It's very transparent. Here, I see someone's roadmap as simple as "Do" "Developing" "Doing" "Done" (with smile face between doing and done.)
