Tim's Disturbing Head
Tim's Disturbing Head is both an image of Tim's head and the logo of Strugglers Wiki.
The original image was taken by Andy in about 1995 in the Forester and Firkin pub in Stafford. Tim's head is, as of the early 21st century, slightly less disturbing. Even when seen connected to the rest of his body.

The photo was made into logo form by following Wouter Verhelst's Hackergotchi instructions, and is pretty crap, but you are invited to do better.
The main motivation for this being that Andy was sick of looking at the default MediaWiki logo for 3+ months.
