Hi there

I am making a intro for my site, and I want to add a cool effect I thought about. I already saw the effect on a other page, but I’ve never really payed attention to it. The effect can be seen @ [http://www.ihearithurts.com](http://www.ihearithurts.com) The preloader you see there is really cool. You can see that the line fills up the further the loading is. I was wondering: how do you make that? Not the preloader part, but just make a animation that makes it look like you are writing some text on your screen. Something like an “invisible” pen. I think I should use a guide line and have a mask follow that line or something? Please help?
