Cliff, I'm never quite sure where I'm going! I'm wallowing around somewhere
between 4th and 5th grade and trying to make students understand big ideas. 

 

So:  Here is my "Slinky"

 

load 'plot'

do=: 13 :'({.y)+(i.{:>:y)*(--/}:y)%{:y'

t=:do 0 10 1000

sin=:1&o.

cos=:2&o.

'pensize 2;aspect 1'plot (sin t);cos t  NB. TWO poolar circles 'pensize
2;aspect 1'plot t;(sin t);cos t  NB. Slinky from two circles over time

 

If I have a Fibonacci sequence (as simple as possible) then I should be able
to make a "Golden Spiral" in 2-D. But if I could start with a 1 inch cube,
could I turn my slinky into a "Snail Shell Spiral"

 

I have found the forum to be the most fun when a problem hatches and
develops with ideas from everywhere.

 

A short take on where I think I may be headed.  Now I'll look at what you
sent.  Cheers.  Linda
