1985 Pen Plotter art. No AI, just Bic pens and 80's technology

Seurat's A Sunday on La Grande Jatte done on a 1985 HP Pen Plotter. No AI involved, just some shading algorithms based on color density. I know the colors are way off - I think the green and red pens are not labeled properly. Also it took 24 hours to do this. Looks cool though.
