[SML] Slow moving motor

[Richard Niederberg]

The easiest way is just to attach a small spot to a master carrier of a
parabola-shaped lightweight curtain track that has its apex tilted upward
from the downstage ends. You are replicating the sun's path. For
automation, you can use a 'Tom Thumb' or other brand motor/gear assembly.
