New advertiser, and a "fun" new way to feature them on the site. We built a Gaiam "skin" for our Mind and Body channel.
I think it's a nice way to strongly brand the page without being obtrusive and getting in the way of the content that the user has come to the site to find. It's also not the most difficult implementation ever - which is nice. The trickiest part was getting the logo on the background image to be clickable. It took an anchor tag being blocked and relatively positioned to make that happen. Of course the hardest part of that was - and isn't everything - dealing with cross-browser DOM/box model inconsistencies.
