Tricks of the trade... I used to post a lot on a forum that was very bad with links. A lot of them would get broken up so you couldn't click them... we found the best way to do it was use sites like that because the forum couldn't mangle links that short.
('twas a copmuter help forum, and it was links to the microsoft website that it hated the most).
As for the Llama song... genius. I see a lot of that sort of thing. I spend quite a bit of time (well, less recently because I keep coming here instead) at the source of all internet creation. The place where such animations are created.
I'll post some links to good stuff in a bit.
