Last year's Philosophers' Rally (Radboud University Nijmegen) 'pop video'

The 2 minute after conference pop video from last year’s Philosophers’ Rally at Radboud University Nijmegen seems to be up on YouTube.

I tend to shy away from audio or video recordings of myself (I do not mind pictures). I think it may be because there is something golem-like about them. What on earth was the figure who looks a bit like me (or the voice that does not sound at all like mine but somehow is) thinking or feeling last year?
