A few weeks ago, the Rotary Encoder LED Ring was released and we are already hearing about projects they are being used in! In case you are interested in getting your hands on one, they are available for purchase at SparkFun Electronics.
We've been fortunate to have a beta tester who has put together some videos of the LED Ring. Some of the videos are quick demos and some are more in-depth tutorials. Here's the YouTube playlist with the collection of videos:
Nick, the beta tester, has also put together an Arduino library for using the LED Rings:

Here is the forum where most of the discussion has taken place about the library. Feel free to jump in on the conversation!
As always, thanks for the support and we look forward to seeing your projects!
