I remember seeing this project here in the forums, but am unable to find it again.
Somebody did a pov display showing a sloly rotating globe of earth.
It would be nice if I could find a link to it.
I also will need some help on how to manipulate a Image so that it can be projected by a ring of rotating LEDs. Or some smart programming trick to read a square image, but display it on a rotating globe, so basically displaying the lines in different speeds to make the illusion of the image beeing a globe.
The basic goal is to display the planets of our solar system.
