Very nice video, great use of slides as mentioned elsewhere. In case someone was going to take encyclopaedic knowledge away from this, the Greek semi-colon is actually a mid-dot-like period character (not exactly mid-dot, as I think that's quite fat). And since we're on the subject, is no separate unicode "Greek questionmark" character, so you'll have a hard time compiling BS 1.0. Although the fix is obvious - through the UTF256 character submission website ;)
