Thanks,
Toby: Thank you very much for providing the source in that download. I'm
very interested in seeing how you've done that.
Achim: Thanks for the guide, I'll try and have a go at implementing it
today.
It does seem very strange how Quartz doesn't have a per character animation
function.
Regards,
Charlie
