I used the brand new and really awesome affine transformation features to create an anmation in Ronin

This is the code i used for the animation which is based on the "transform" example

(resetTransform)
(clear)
(move 300 400)
(defn branch
  (v l)
  (if
    (gt v 0)
    (
(def a (add 50 (mul 30 (cos (time 0.0007)))))
        (scale 0.95)
        (stroke
          (line (pos 0 0) (pos 0 l))
          1 "white")
        (move 0 l)
        (pushTransform)
        (rotate (div v a))
        (branch (sub v 1) l)
        (popTransform)
        (pushTransform)
        (rotate (div v (sub 0 a)))
        (branch (sub v 1) l)
        (popTransform)
    )
  )
)
(branch 10
(add -20 (mul -10 (sin (time 0.0007)))))
