I don't know if I understand your method exactly but I did a similar
thing with a reasonable result using sin/cos-functions. This gives a
nice curve. The position of each sphere is based on its place in the
string _plus_ a clock value. This way the first sphere will move also.
This is easy to avoid by moving the whole string relative to the
translation of this first sphere. Sounds far more complicated then it
actually is 8)
