Check out my Awesome Raspberry Pi sign with 96 LED's and a User interface! The interface is served up by a Pi. The Pi sends updates to an Arduino which then controls a 3m strip of RGB LED's! Thanks the the guy's at www.jayconsystems.com for the help!
Here's a link to the video on my blog!

Very well done!
Is the code /schematics available?
Well, I haven't made them available because they need alot of work to make better, I'm still a novice at all the languages it took to make this happen. I just kinda crammed and hacked it all togther. Here is how it works.
(1) The Pi serve's a webpage built on the Django Framework. The Pi takes request and returns Html, css, jvascript code.
(2) The afformentioned code creates a user interface using vector graphics. When ever the user interacts, like "Pressing a button", the info is sent from the browser to the pi using ajax. The Pi then updates a Mysql database.
(3) When the database updates a serial command is sent to the Arduino via the usb cable, and the Arduino issues the corresponding commands to the LED strip....
It's alot of stuff that I'm novice at, but I made it work. I have to refactor it before I put it out...
