Curved/Circular LED Matrix

Hey everyone, 

I've been interested in making a new project using an LED display, however, I have no idea how to go about such a matrix without the proper instructions or guidelines since it is very different from a square or rectangular matrix. I was hoping someone could explain how to wire and go about making such a thing (programming advice would also be appreciated).

With a rectangular matrix you have columns and rows.
With a circular matrix you have rings and sectors.
A circle would be no different than a square. Just the outside rows and columns will have fewer LEDS than the middle ones. So you'll ignore those address spaces on the shift registers.
