To go even more off topic - we saw Joe Strummer and the Mescaleros at Glastonbury - there was a massive overhead camera on a boom above the band, filming for the big screens around the stage, which kept getting closer and closer to Mr Strummer 'till in the end he picked up his 'mike stand and smashed the base into the lens. All the big screens fickered and went black...
He had warned them...
Still. looking forward to your presentation!
Cheers,
