As WordPress grows, it becomes possible to make more and more sites using the technology. Pages and the permalink structure give it CMS power, custom taxonomies and post types expand this further to differentiate chronological posts, pages and arbitrary objects, and plugins fill the gaps.
So, you can use WP to power your blog, photo gallery, and website. What are some of the more creative uses you’ve seen that exploit powerful WordPress features? What are some sites that made you say, “That’s WordPress?”

Have you taken a look at http://wordpress.org/showcase/ ?
There’s a ton of “that’s WordPress?!” sites there.
I also found:
WordPress as a QA site

WordPress as a Ticketing system

Although these examples may not be surprising to long-time WordPress users, new users may find them interesting, so I figured I’d list them. I sometimes use such examples with clients who are unsure of WordPress.
Ecommerce Sites
(I pulled these particular examples from the Shopp plugin. There’s also the WP e-Commerce plugin, for those who are interested.)
Social Networking Sites
(These are powered by BuddyPress, which sits on top of WordPress. I’ve also heard of the Mingle plugin, which supposedly does something similar, but have never tried it.)
Here’s one from a local record company (Portland, OR).

As a product display website for a small business. For instance, with this site, I composed it with the PODS plugin and a custom theme I designed myself.
