Rotating Lighthouse with LEDs?

I bought some LED strip lights  They let me cut them apart in bunches of 3.  I was hoping i could cut about 8 to 12 of these 3 Led sections and create a led lighthouse.  I just want to have a way for them to cycle on and off so it looks like it is rotating around.  I am going to stand the pieces up and down all around the lighthouse light area.  But i cant find any instructions on doing something like this.  Each three led section would need to turn itself on and off in sequence.  Or 2 or 3 can be on at once if it is easier just so it looks like it is rotating around it.  I would like it to go slowly around like a lighthouse

Does anyone have any idea on how to accomplish something like this.  These new strip lights are very bright i was surprised how bright they are.

Member Iceng posts a nice circuit for this. This 'ible discusses it
