The AIGA Atlanta website was built from the ground up with an eye on using web standards to their fullest—the idea being that such a center of Atlanta's creative community should be a worthy example. Even the Javascript-based rollovers use no inline scripts, instead walking the DOM tree to create the necessary event handlers.
The result is that AIGA Atlanta is one of the first (possibly the first) AIGA chapter sites with an accessible, standards-based site.
