I've spent a bit of time making a new version of blam! - this one runs locally on your own server, so you can customise the templates as much as you like. It still uses Amazon for its data, so if that bothers you stay away for now.
You can try it out here, which posts to a test blog.
All feedback gratefully received. I'm also looking for volunteers to test it on their own site, whether Movable Type, Radio, Blosxom or whatever. Send me an email if you're interested.
