I am creating a new theme based on the current one that was actually a recolor of the old Streetrat 1.0 theme that in turn was based on a WordPress 1.5 theme that is not updated anymore. And since the WordPress team landed at version 2.1.x I felt it was time for a major overhaul.
I have no schedule set for completion but I hope to complete the redesign somewhere between Friday and early next week.
This is way you might see different color schemes or images in the sidebars and header when browsing trough the site. That is not your computer bahaving odd no need for alarm.
