Are you bored with the theme choices? Well, three themes were just added. Simpla, Jentri, and Rubric Updated. Rubric Updated is my update of the Rubric theme based on the work of Hadley Wickham and Tom Raftery. You can download Rubric Updated here.
If there are themes for WordPress 1.5+ that you like and would like considered for addition to the site, leave a comment.
