I put together the SimpleDE project for OpenBSD. It was based on a similiar project in the FreeBSD forums
Distrowatch labeled it as being an effort to make a more suitable desktop for OpenBSD but actually the effort was to use the available tools in OpenBSD to put together an easy to use desktop. There are no wrapper, cludges hacks for systemd, pulseaudio, hal, udev. It runs well on older systems/video cards and does not require compositing.
Doing away with the overhead for systemd, hal, udev results in a very light weight system that occupied < 80mb of system memory at idle. Since it does not poll menu items it is extremely responsive. The desktop was modeled after OS/X and in my opinion is very intuitive. For example, clicking the envelope icon in wbar starts a simple, easy to use email client.
There was also an attempt to educate the user about the configuration files and their locations, links to the FAQ documentation and how to use the man pages. Most of the configuration files were centralized which makes is possible to set up the same desktop in other distro's. I have set it up in Fedora 20, Debian Wheezy/Jessie and NetBSD.
