Openbox is a little different than the other *boxes. For some reason, I don't like the way that Fluxbox, Blackbox, Waimea, etc. handle windows. It just feel weird to me. Openbox handles them how I want, though, and does it very nicely. It's also really easy to theme for (like all the *boxes) and is really configurable. Plus, like all the *boxes, it's very resource-light. You can get it at http://www.openbox.org Here's a screenshot of it (running xftaskbar4, too)
