Fluxbox is a fork from Blackbox, wh/besides being a nice light wm in it's day, also gained fame because it was Stallman's preferred choice (no clue whether this is still the case). Flux is highly customizable and attracts users who really like to tweak and tune their desktop. Hence there are a LOT of flux themes out there and it maintains a pretty fiercely loyal following. It's what I used back in the day, post Blackbox, and before I switched to OpenBox.
There's a lot to be had for the "roll your own" approach if you have the time and inclination. Just be prepared to spend some time in "man" and digging into various config files - a great way to increase one's understanding of what goes on "under the hood".

I know right where I'd turn
