I'm working on a new theme that is closer to a lot of WordPress looks out there.
Right now, I've going with a zero-image look to see what I could accomplish without using images for curves. So far it's looking pretty boxy, but the colors aren't too bad. I decided to use curvyCorners instead of images to round things out. Since this is primarly a blog about coding, not design, I think it's appropriate that the design doesn't have a lot of imagery, and that the site uses code to accomplish its look.
BlogEngine.NET makes skinning the site super easy since it's basically just a MasterPage and a CSS file. I also made a small change to the tag cloud and created an alternate version of the recent comments control so it just has the author and post title.
