ANN Spring things

[Jim Hurley]

I have been working with springs and have developed a few utilities 
which might interest others.

The iconic spring is easily described geometrically, but difficult to 
describe in terms of its Cartesian coordinates and so they are a good 
candidate for Turtle Graphics.

For some of applications, the raw coordinate geometry of Run Rev is 
much too difficult.

Included among the applications:

*How to design shock absorbers
*A commercial for Run Rev: It is revealed in the answer to the 
question: "How many programmers does it take to change a light?"
*A jack-in-the-box

P.S. Don't you people ever sleep? I'm having trouble keeping up with the list.
