Edit again: One thing that's sort of implicit in the instructions but
needs to be made explicit.  The script can handle lots of motions at
the same time.... in other words, you don't need to apply it separately
to every part and parameter.  You set any or all parts of the figure to the
position you want at "one end" of the cycle, hit the Mark 1 button; then
set any or all parts to the opposite end of the cycle and hit Mark 2.
The script then creates the oscillation between those two positions.
