I like The Man in Blue’s header. A ‘Page Options’ tab elegantly opens to reveal some style sheet options.

These look like accessibility-driven options but it got me thinking that this type of design could be used for other options:

• standard utility features such as Contact, About, Sitemap
• inter-network links for a site that is part of a bigger grouping
• page info?: last updated, author, copyright
• more accessibility options such as font-resizers
• print me, blog me, del.icio.us me
