Or keep the RPM the same and have 3 strings, each of a different color. O=
r have
twice as many strings as colors and cut the RPM in half.

With multiple strings you could use multiple processors, each displaying =
a
version of the image rotated by the angle between the strings. It would b=

to keep all of the uC's sync'd if they run the same code and see the same=
