These are things I've found on the Internet. Look upon my works ye mighty and despair.

Japan’s Ubiquitous Entertainment Inc. is prototyping an iPhone-based navigation system for cyclists. The “iPhone Arider” couples a stock iPhone with Scalar Corporation’s model T3-A retractable head-mounted display. The handset runs the GPS app of your choice and routes the video to the eye-level viewer. Bikers can also make and receive hands-free phone calls via Bluetooth, and even use the TwitBird Pro app to get push notifications from their Twitter stream. (via Heads Up!
