From Waimea website:

Waimea is a highly customizable window manager for the X Window system
conforming to the latest EWMH specification. Waimea supports multiple
virtual desktops and by using the cairo graphics library for all
rendering, waimea provides a modern vector-based style engine that
takes advantage of display hardware acceleration when available
(through the X Render Extension).

The screenshots are clean and simply beautiful. I’ll update my freedesktop CVS copy, recompile and test this WM. Until Aegis reaches some usable state ;-)
