because a picture speaks a thousand words and a video...

Here is a description of the pieces that are working and a rough outline of some of the todo’s, but to make things clearer (and quite frankly to show off some of the good bits) I’ve included a short video with a commentary covering some of the more interesting stuff.

Apologies to the BBC (it’s their multiplex) and to MGM for reproducing their material (I’m sure they’ll be in touch if it needs to be removed.)

If you have problems with QuickTime, then a Windows Media Format version is here.

NOTE: this is a developer code release, it functions but needs to be nursed along and tweaked, it’s a million miles away from end-user consumption.
