Advanced Theme Construction Kit (ATCK)atck was developed in a production environment for purposes of quickly building css and xhtml valid Drupal themes from scratch without having to un-theme an existing Drupal theme to do it.
atck components:

1. WYSIWYG grid builder
A browser-based grid builder which produces starter code for a page.tpl.php file. The grid builder itself was originially built by Christos Constandinou and it uses a modified version of Yahoo Grids which is more flexible and easier to customize. With Christos' permission (thanks, Christos!) it, and the supporting css, has been customized so that it works for Drupal themes and so that it is css3 valid. Access the builder online (FF only!), or download it and run it locally. [builder cannot be on Drupal.org because of MIT license]
2. style.css [separate download because of BSD license]
style.css contains only the css needed to support what the grid-builder outputs, as well as some general 'resets'. The only modifications one should need to make here would be if they want to make their layout a fixed width and/or a different width (default widths are in %).
3. page-layout.css and template.php
These files are where the visual styling of the site happens. The source of these files is from a combination of code from the Hunchbaque theme and some changes/additions which I added in order to provide baseline settings I prefer and/or provide more granular settings. The beauty of these files is the simplicty of them - they include as little markup/styling as possible to avoid complexity, while at the same time putting many helpful tools/comments at your finger tips so that you can accomplish what you want.
4. page.tpl.php
A sample page.tpl.file is included as a reference for finishing your own page.tpl.php file using code output from the grid builder. Note particularly the variable names for the blocks, regions, menus, etc. (at this point the builder does not include those items)
5. fix-ie-6.css and fix-ie-7.css
These files are included for purposes of providing IE-only css to each of the respective versions. By using conditional comments like this we keep the main css files hack-free and atck css3 valid.

The theme validates XHTML 1.0 Strict / CSS 2, and it is cross-browser compatible; works perfect in Firefox 2.0, IE 6, IE 7, Opera 9, Netscape 8.

This is a port of the andreas01-theme as found on http://andreasviklund.com/templates/.
I'm not very active in maintaining the theme (sorry, but I don;t want to disappoint you by providing little support and you not knowing)', partly because this is fairly new stuff to me, and PHP is not my main thing, and not even second...
Requires PHPTemplate.
This theme validates as XHTML 1.1 Trans and valid CSS 2.
The log-table has been set to a font-size of 6px, to make sure it fits on screen.
I will try to have this theme compatible with the core-modules of Drupal.

The art4 blue theme is 2 or 3 columns theme based on the Danger4k theme.See in action and on demo site

This theme creates a way sites who have .mobi aliases of their website to have a specially formatted mobile format for their visitors who use the .mobi domain, and allow the visitors of your .com/.net/.org/etc to still see a fancy or complex theme.
This theme is intended to be used with the mobi loader module, though it will also work fine without it as long as your intention is for all your users to see the mobi format. When paired with the .mobi module, the module overrides the default theme to display a mobile, portable format from the mobi theme.
Requires: .mobi loader
