mikemurko: Yeah, it appears that this rendering got messed up. I'm going to re-render tonight and see if I can fix those issues. (Dam OSX, played fine here, but after a restart I see those issues). As for the question at 2:45, I had meant "the key series", meaning the key-stream that needs to be communicated.
For some reason audio is mono on the left speaker. Good video though. One comment - the speed of your explanation ramps up from slow and easy to kind of confusing at around 2:45. When you say "the series that we're adding to" do you mean the "cipher text" above? I think you rush things on the public key side. Otherwise nice job!
