He only contributes fairly irregularly to ZFC - but tends to be remembered for the fact that all his postings are always exactly 74 characters per line, regardless of subject or length!
Douglas was previously a 'Quality Assurance Manager', but now runs his own "Human Sundial" business. This began by accident only as a hobby, but now operates full-time, internationally. If anyone is unsure what a Human Sundial looks like, it actually uses a person's own shadow to tell the time. You can see examples of these on his web-site, where the 'Picture Gallery' area illustrates many examples of this novel feature, which could be of specific interest to Schools & Gardeners.
