UPDATE: Lloyd Budd points out that these are not really open source.
OSWD is a bunch of open-source web designs, most of a bloggy style. There are more than 2000 of them so far, and you can contribute your own—at least if you have better web design skills than I do.
Thanks to Bre for the link. Here's a nice example, called RedTie.
