Geocities site cleanup

Late spring holiday weekend, and another spring-clean. The brushed-metal look was too oppressive as it stood, so I've toned it down, and added a dash of colour. Page layout is now done with CSS on modern browsers - thanks to the CSS gurus at alistapart.com, bluerobot.com, and thenoodleincident.com for the hints, tips, worked examples and design philosophy.
FWIW all pages are now XHTML 1.1, at least until the hosting service's scripts start.
