Hope this video works. If not. post #19, go to link, go to bottom.
Think on this: 5 LEDs facing different directions. All LEDs are driven with the same current and produce the same light. When five people standing around the light house, they will see the same thing at the same time. They will think the light moves in a circle but it does not. (fake and in your head)
LED current timing, 0,0,0,0,1,2,3,4,10,10,4,3,2,1,0,0,0,0,0,0,0,0,0,0,0,0,0,0, repeat.
Watch the video and think "not spinning". Now think "spinning".

You can make 5 LEDs do the above pattern 1/5 out of phase. I think each person will see the same thing as above.

What do you think. Does a stationary light house rotate in your head because you are programed to see it rotate.
