TUMIZA is a red and brown corporate site theme designed for GuruMarco.com. It started out as a web design mockup that I cleaned up and now-ized, but with varying requests from the guys at GuruMarco it eventually evolved into a more 90s-ish, compact, darker theme.
Tested in IE8, Firefox 3.5, Opera 9/10, and Safari 4.
