[Fluxus] Turtle builder

hi Luis,

you forgot to create the vertices and build the object. something like 
this might work:

(clear)

(backfacecull 0)
(hint-unlit)

(define (spiral n)
       (turtle-move (/ n 20))
       (turtle-turn (vector 0 0 15))
       (turtle-vert)
       (if (> n 30)
           1
           (spiral (* n 1.02))))

(define (build-spiral n)
     (turtle-reset)
     (turtle-prim 0)
     (spiral n)
     (turtle-build))

(build-spiral 10)

i also made the spiral a bit smaller, to work better with the default 
fluxus camera settings. the turtle turns around the z-axis now, so you 
can see the result without rotating the scene.

you might find the turtle chapter of the fluxus documentation useful.
