I'm pleased to announce the release of my first WordPress theme today — Brave New World. The theme is free of layout and styling beyond a modified version of Eric Meyer's reset CSS and two baseline typography CSS files to choose from — just like Elliot Jay Stock's Starkers theme this is a base theme free from cruft yet incorporates HTML5, WAI-ARIA landmark roles and hCard and hAtom microformats.
This theme is provided as-is, with no promise of support, although I'll help out where I can if Google can't help you first. I hope you find this useful, please let me know in the comments below and spread the word if you do.
Download the Brave New World WordPress Theme here (98Kb zip file). I've ran my anti-virus over it, but so should you.
Update: 7 April 2009
I made a slight amendment to the CSS reset today in light of the work done by Jacob Rask regarding the removal of elements no longer used by HTML5.
