Agencies like nothing more than reinventing the agency site. We've seen the drab, Flash-heavy, barely usable site recast as a blog, a YouTube channel, a Facebook page and a Twitter stream. Now, TBWA goes with the slideshow. The shop created a new "storytelling platform" that underpins the site. The end result looks a lot like a slideshow to me, although it does have the flexibility of showing work in a coherent fashion with a mix of media. Overall, the navigation can be a tad confusing. It's still quite a bit better than your run-of-the-mill agency site with a runaway pencil.
