L.E.D. Wall clock idea

I saw this clock design the other day. It was a circle with the clock hands in the middle and unattacked to the clock there were dots around it to mark the hours. I want to improve this design by making the hour dots light up on their respective time for the whole hour. Maybe make them have a nice dimming transicion between the hour switch at the last second.
I don't know much about programming L.E.D.s or what hardware I would need. Can somebody help me how to make this project?
