The pretentiously-named Zeitgeist Clock claims to be the "smallest museum in the world." How so? Well, it stores artwork on it that is then shown throughout the day. It's called a clock, so I assume there are clock functions as well, but where they are on the product itself isn't exactly clear from the photos.
These things are very limited edition, so that gives the designers an excuse to charge between $467 and $675 for them. Are you serious? You could buy some real artwork for that much, artwork that isn't stuck in a dinky alarm clock.
