Say what you want, think what you want, feel what you want about the rock band Tenacious D.
But when it comes to the design of B2C websites, I don't know that I've seen anything lately quite as fresh and innovative as The D's promotional website for their new movie. It just could be the greatest website ever created.
Instead of the usual cluster of clickable static pages, we get a story, some humor, a lot of fun, and above all, an experience. An almost cinematic experience. It's the Tenacious D brand writ large, dude. It's like inward singing but for websites.
( update 11 October 2006: in the grand tradition of The D, parts of this post were written tongue-in-cheek. Humorous. As in, it's probably not the best website ever. Because of this, I'm not going to be able to respond to every email and blog link I receive assailing my marketing and aesthetic tastes. But you have to admit, it is pretty cool. )
