Thanks for that link, there's a whole load of stuff I'd never heard about
before there.  I wonder if it's possible to implement that vertical rupture
(sounds painful) thing on a Beeb then?  And if so, why did Orlando never do
it? :)

I'm going to have a play with that when I get a chance.  Meanwhile, any luck
on the Firetrack scrolling thing Tom?

Cheers,
Rich :)
