The Rössler Attractor (printed version). Here is a plot print of this image: https://www.instagram.com/p/CHJQov_Fly_/ The vectorial svg file to print was generated using Turtletoy here: https://turtletoy.net/turtle/c82f5e2af3 #plotter

u/rodrigo.siqueira

Comment by "themarinus" (he printed the image using a pen plotter): "The Rössler Attractor. This beautiful design is made by Rodrigo Siquera over at turtletoy. Loved it so much that I turned his line art into a plot! 160 grams A4 black cardstock White acrylic ink, with a 0.5mm line width."
