RGB LED globe

I have been distracted today by an idea to make a globe (any size) out of RGB led’s which would be addressable by lat/lon coordinates. I found a story about these guys who built a single 40 led ring which rotates – at a certain frame rate – with 200 addressable positions – ie., 40×200.
