Hi there Paul,

I appreciate your concern about the usage - I neglected to think of that. Sorry for being a bit inconsiderate!

Having said that, it probably won't be necessary anyway - it looks as if Chris has actually posted a short video on his home page, so I won't need to for the moment.

What I think I'm going to do is borrow a digital camera and do the same (stick it on my homepage), then post the URL when it's up there.
