For this animation I used the new ellipse command in ronin and created some retro style neon vector line art

The neon line was created by drawing the shape twice first with a higher line width and a low opacity then again with a linewidth of 1 and full opacity to add the glow around the line

this is the code I used for this animation

(on "animate" '(
(clear)
(map
(range -60 60 10)
'(
(def ofs (mul 60 (sin (time 0.001))))
(def r1 (add (add 120 ofs)  %1))
(def r2 (sub (sub 120 ofs)  %1))
(stroke 
  (stroke 
    (ellipse 250 250 r1 r2)
  (rgba (mul r2 2) (mul r1 2) 200 0.1) 10)
(rgba (mul r2 2) (mul r1 2) 200 1) 1)
))
))
