I changed the default Zonelets theme! Originally it was "Purple Paper" but that felt not "defaulty" enough to me. So here is the new default theme: Diamonds. It has a nice feature where the background image is a transparent black diamond. This means that you can just change the background-color attribute of the body tag and it will still have a nice diamond pattern: you aren't "locked in" to the bluish-green.

I also updated the theme pack to conform with the starter files, which as of 1.1 have relative links, allowing you to preview Zonelets on desktop and have them in subdomains--version 1.0 of the starter files and themes would only work in the root of your site.
