FileMaker Pro is used to hold the album information, and then various home-grown Ruby scripts export that to html (with a little help from Markdown). Other Ruby scripts create some of the tabular pages, such as the time-lines.
The pages use Cascading Style Sheets extensively, which means that they should look a lot better with a CSS aware browser, but will render fine on any browser.
