Who knew the new Google Patent Search feature could be put to such fun use. Apparently, the folks at Ironic Sans have culled a bunch of patents filed by celebrities. I'd heard about Mark Twain's self-pasting scrap book, and Harry Houdini's diving suit, but I'd never heard of Zeppo Marx's cardiac arrest monitor, Eddie Van Halen's musical instrument support, or even Danny Kaye's super-sized party favor. There are tons more, with drawings, if you follow the link. Via Boingboing.
