I've been having a closer look at Blogsphere V3 over the last couple of days. It really is a well put together database design. The thing which has impressed me most is the Movable Type skin support. You can just go and download any Movable Type skin (a good place to start is here), copy the css files into a skin document and save it. Or if you want to make your own style, then go here and play around to your heart's content. This is going to keep me entertained for months to come!
