I was a bit awkward with the placement of the screen and the designated speaker area. I kept wanting to step up to the screen and point at it with my hands, which is what I did in the previous iteration, more like a whiteboard presentation, but then I would have walked off-screen and either way I would have needed a teacher's pointing stick or laser pointer to even reach the relevant parts of the slides, because the projection was so large and so high up.
Anyway, I'm glad I did it. It was very educational for me, both preparing and giving the presentation -- my ideas around #flowglue
basically come from me thinking about this presentation -- and it got a few people interested.
