[Fluxus] Turtle builder

[Luis navarro del angel]

Hi, 

I'm was trying to use the turtle builder, and i was wondering if it can be used 
with the ordinary turtle commands (forward, right, left, repeat etc.)
I found part of this code in the web but i can't make it work, i don't know 
what is missing.

(clear)

(define (spiral n)
      (turtle-move n)
      (turtle-turn (vector 0 15 0))
      (if (> n 30)
          1
          (spiral (* n 1.02))))
(spiral 10)

(define (render)
      (turtle-reset)
      (turtle-prim 0))

(every-frame (render))


greets, 
Luis
