Open Source Web Design
They go on to say in their About Us page: "The Open Source Web Design project was founded in September 2000 by Frank Skettino (bkenoah) as a way for the average Joe-Hacker to have a quality, organized web design template ready for him when he's ready to share his ideas on the World Wide Web. We understood that many hackers would like to have a place to share their ideas on the Web, but are too busy to create a decent layout. This results in a poorly organized page or none at all. With OSWD, we hope to solve this problem."
You can browse thumbnails of the member-contributed design templates (92 pages of them!), check out the most popular designs, and even rate them. I have browsed 60 pages of thumbnails so far, and I think it's safe to say there is something for pretty much any taste. If you have content needing a container, you may need to look no further than OWSD.
