"Unfortunately it fails at being quiet and reliable, which is a very important quality of a useful timepiece."
Previously, previously, previously, previously, previously.
Neat! One of my favorite contemporary clock re-imaginings is the Corpus Clock/Chronophage:
Nice. I'm kind of baffled that none of the "previously" links are to one of these types (many related vids), because it seems like the kind of thing I'd have stumbled across via your blog. I love the way they glow.
Making the cutouts the digits is a nice variation. I'm not sure why it shouldn't be reliable, really, unless it's badly unbalanced the platter or something.
Speaking of clocks, one would think this would be fairly high on the "things to get JWZ for the next gift-giving occasion..."
