Normally, I hate it when web designers get clever with navigation. I don't want to have to figure out your Flash-based navigation system when I visit a site; I want it to behave in predictable ways when I visit so I can find what interests me. I want it to be fast. Watching a "site loading!" graphic when I just wanted some basic info usually makes me just leave the site altogether.
My goal is to find what I need, not to sit in awe of your design prowess and conclude that you must own more turtlenecks and cool shoes than the other designers. It's not about you, it's about me.
That said, I'm really not sure what I think of this site for some condos in Atlanta. It has a funky layout that feels like sliding around a globe. But it works well, is kind of cool - and is supplemented with a more traditional set of links up at the top. (I wonder if that was something that the designer didn't want to do but the client insisted on.)
What do you think?
