For those who weren't in attendance at Drupalcamp Vancouver last month, Mark, Hubert, and myself prepared and presented a production version of our internal base theme that we use for client development called "Base5".
Since then, Hubert has fine-tuned the theme in preparation to contribute back to the community. We've also changed the name to "Basic".
Basic boasts a clean and simple HTML structure with a top-down load order for improved SEO and features a table-less layout with the option to either have a fixed or fluid width.
This new theme is freely available in both Drupal version's 5 and 6 and provides only the essential functionality found on the current ZEN theme (located on drupal.org).
Note that the work being done on Basic is by no means a fork of the much appreciated efforts being produced towards the ZEN theme. Basic's goal is to provide themers the building blocks needed to get their designs up and running quickly and simply.
Take a look at the Basic project page and tell us what you think.
