This looks pretty interesting, taking some of the Dagi "see through" idea but letting you hold the stylus at any angle. No pricing or availability info yet. I've written them and can report back here when I get a reply.
EDIT: I talked to the inventor this morning. He's a jeweler who basically created the example on his site himself. He's tested it with some friends with good results. The big issue now is manufacturing. He's planning on doing a very small run himself initially (he estimated a couple dozen), then gauge reaction/reviews and see if it make sense to contract with a manufacturer. Obviously, the cost for the handmade ones will be significantly higher than the Pogo/Dagi pricepoint, but if he does go into a partnership with a manufacturer subsequently, it will bring the costs down significantly.
He's had quite a bit of interest as his stylus was featured on Engadget, so he's just compiling a waiting list based on emails received and will go down that list as he makes the initial batch.
