Multiple reasons to check out David Friedman’s various web nodes:
The very funny and very clever Ironic Sans: e.g. his proposal for a motion-sensor alert-signal-adjusted mobile phone; the absolutely brilliant fiber-optic streetlights ((When the Administration launched its broadband stimulus bill, this may be the single application of fiber that wasn’t foreseen));
Thsrs, “the on-line thesaurus that only gives results shorter than the word you look up” (I’d been thinking that telegraph abbreviations and shorthand were due for a comeback, anyway);
David Friedman Photography – we’d do you a disservice by producing thumbnails, go look already;
and his photography blog, David Friedman Photography: Blog. Recent posts are his series about inventors.
