Bill, may I call you Bill? I am an instructional designer (teacher of teachers) at a Technology School in Oklahoma I think your video style would be VERY engaging for students. Have you ever given any thought to teaching teachers (or teaching teachers of teachers) how you create videos for instruction? If teachers presented information in the same style as your "History of Japan" video, students would watch it multiple times. And/Or, would you consider doing a video chat with some students in a digital media classroom?
sure.  i will teach anyone things if they think i know them.
