I've mentioned before my employer's channel on YouTube. There's now about a dozen videos that have been made over the past year, either as dry runs inhouse before ANTEC or at an all-day technical session that we did for the local SPE session. The former talks are more in-depth, the latter are introductions. The come complete with disclaimers that our legal department added! Never seen that before.
I've also never seen myself on video before, well I have come to think of it, but just in home movie type things, never a full technical talk. Quite a strange out of body (literally)experience. I have less hair and body mass than then too.
