A comment on At M.I.T., Large Lectures Are Going the Way of the Blackboard. Parent comment
One thing though, when there's direct light, what's written on the surface casts a shadow on the painted back-side. It looks a bit odd.
Also, the same effect results in a fuzzy picture when the glass board is used as a projector screen.
I'd love to experiment with back-lighting the glass board. If would eliminate the shadow-problem, and look pretty neat, I think.
