I don't know who or what The Register is, but they made the video private which has me unimpressed. If they're hoping to bash someones attempts to get girls interested in science then perhaps they should not hide the video they're presenting.
On the other hand, the video on the first site you linked to had, as far as I could see, one picture of a lipstick and it was in the presentation name. I thought it was a good idea. If connecting the things girls are interested in with science works, then why not?
Perhaps I missed something.
