The Segue Project has created a number of themes for various platforms including WordPress, Moodle and Mediawiki.
I’ve created two themes for WordPress. ShadowBox is a theme whose principal design motif is that of a foreground box that drops a shadow on a background. Translucence is a theme derived from Twentyten, the WordPress v3x default theme. The primary design motif of this theme is that of a many foreground boxes of varying opacity on top of a background.
Both ShadowBox and 2010 Translucence include a WYSIWYG theme options editor and can be used as parent themes. Translucence will eventually replace ShadowBox. For more information, see:

I am currently working on a version of Translucence for use with MediaWiki…
