Cool, most interesting! Thanks, Chris! Let us know when it's published (has it been online, yet?)
Yes the file size was most what I was concerned about in Edge. I haven't yet had to create any of these types of ads yet for clients, yet I know they'll be quite popular, very soon (and file size always a concern). I've only made some test ad banners in Edge in other previous beta versions. Maybe Adobe has improved on it since then too. Also with GreensockJS that's another thing, too. So, thanks for your explanation of the Publish feature. It will be handy.
Thanks again for the tutorial, and keep us posted!
