Man, is this thing gorgeous!
This keyboard was commissioned by a female client and has some elegant, feminine design features such as violet LEDs, an acanthus-leaf pattern etched into the brass, and a soft burgundy wrist pad that is removable for cleaning. It also has a built-in "buttonless" touchpad mouse in the center (tap anywhere to left-click and drag, tap in the top-right corner to right-click). This keyboard is interesting because the typing plane is actually tipped forward rather than back. It looks odd at first, but actually makes for a very comfortable typing position.
Datamancer has been cranking out a lot of great keyboards in the last year, but I think this one really takes the cake.
