Bestill My Beating Heart

Perhaps not the best centerpiece for the next family gathering (unless your family is like mine, in which case it'll be a competition to see who can get the display open first to see how the heart actually works...), but a cool piece nonetheless, created by artist Billy Chasen for the American Heart Association's 2008 Heart of New York Gala.

Billy has some other cool work worth browsing, too, including an exploded iPod set in resin that still works, and a marvelous and rather mindboggling piece called Weight of Words. He also has an interesting blog that covers ground from social commentary to art (which you might argue are one and the same).
