Check out this RasPi circular LED display project tutorial from Thomas Mardis. The Cloud Lamp Project:
After getting my home somewhat automated with a z-wave network and a few other custom devices, I thought I’d like to have a simple way to see the status of my home, the weather, surf report, etc, easily visible from my bed. My initial thought was that I’d buy a conventional ceiling lamp and put four rgb LEDs around the perimeter of the lamp as status indicators. Well, two weeks ago I came upon Make’s contest and even though I was already behind I thought it’d be really fun to try building something. So I took my original idea and made the following changes: I went from 4 to 60 rgb LEDs after being inspired by this beautiful clock. Well, that and I love circular LED displays! I probably wouldn’t use the analogue-like clock functionality but I thought it was a beautiful design and I thought I could add something to it. And of course I changed out the Arduino for a Rasberry Pi, which made the project amazingly versatile! …
