My latest premium Posterous theme, Delphos, is now available. It has some nifty features that help keep a clean layout while still providing easy access to all the functionality that Posterous offers. Here's what it looks like:

I personally love having the Tweet and Like buttons easily accessible, but tend to think they're a bit of an eyesore, so I went ahead and created a Sharing panel.

Along the bottom is a bar that handles the subscription, profile, links, search, tags, and archive blocks, all accessible with a rollover of the mouse.

I think Delphos is a great way to keep all the functionality of Posterous on your site without the clutter. You can purchase Delphos from my Posterous theme store here.
