On April 9th, Rubiqube.com (Adrian Diaconescu) released the free WordPress theme: Corporate Sandbox.
Corporate Sandbox
Based on “The Sandbox” by plaintxt.org, Corporate Sandbox is a minimal, clean, widget-ready, valid theme suitable for corporate blogs. It has cross-browser support, and I’ve tested it on WordPress 2.5 and 2.3.3 with success. Adrian was kind enough to implement some changes that I’ve suggested to make the theme more customizable, and so, he recently released the 1.1 version of this theme.
