I've looked at it using a sacrificial browser and I haven't a clue what's being demonstrated.
I /think/ it's some version of Linux running KDE, hence is possibly germane to the problems in Gus's thread.
PLEASE could we have more details, preferably with demonstration code and a full description of what OS etc. is being used.
I'd also suggest that reporting a potential problem via a public channel such as Youtube, rather than raising it in the forum or one of the mailing lists, is an extremely reliable way to make oneself highly unpopular.
