Sprials, Revisited
------------------

What happens when we write?

   (define action01!
     (lambda (t n)
       (turtle-forward! t 1)
       (turtle-turn! t n)))

   (for-each (l-s action01! tommy) (iota 400))

Hypothesis: Gets tighter and tighter and tighter

Hypothesis: Once we reach 360, we'll get another straight line coming out
