One of the "sweetest" navigation designs I've ever seen comes from Seattle-based ski & board shop Evo.
You can click the classic Valentine candies' logos right through to categories like Rossignol, K2 and DC gear.
Super creative. I "love" it.
Evo's also done a nice job with its About page, complete with YouTube video. The customer service peeps each have their own Polaroid mugshot and bio. It looks *almost* as fun to work at Evo as Elastic Path!
