I have just released a new public theme for use called "Elegant Flame". It was originally a theme I used on my blog up until recently when I deployed my own custom theme.
It has been redeveloped to be widget ready with 5 widget panes. It has support for the Gravatars2 and Popularity Contest plugins built it but does not require either to function.
Released under CC BY-NC-SA for free. Hope you enjoy. and let me know if you like it, hate it or have problems with it.
