Sent you a power point, Google calls them a Presentation. I assume that by Tuesday sunup this will be 100% changed or discarded. But I think it is about the right length. Powerpoints are incredibly offensive; it is like being asked to read a child's book projected on a screen. It's even worse when some nervous guy stands at a podium and reads the screens aloud. So needs to be pretty short.
The other things that might be useful:
A couple of diagrams, as discussed
Three or at most four blog-length prose pieces by you. Don't need to be new, but we need to review the canon and see what hasn't been addressed in the best existing pieces.
A couple of six minute videos where I ask you scripted questions, but the answers will be unscripted and mostly unrehearsed.
And hopefully you can request to make a live presentation by video hookup or in person (tell Green to send his Gulfstream to get you).
