In cj-holmes/spiraplot: Reproduce Images On Spirals

spiraplot

The purpose of spiraplot is to create an image on a spiral where the spiral line gets thicker and thinner (representing dark and light areas of the image). I’ve seen these types of images before, and this is my attempt at creating them in R. The engine behind this solution is the rather splendid simple features {sf} package.

It is experimental and may not work properly

library(spiraplot)

Use an image of Einstein for demonstration

einstein <- 'https://upload.wikimedia.org/wikipedia/commons/thumb/d/d3/Albert_Einstein_Head.jpg/800px-Albert_Einstein_Head.jpg'

spiraplot(einstein, aspect = "portrait")

You can make interesting images by playing with the spiral_turns and spiral_res

purrr::map((3:6)*40, 
           ~spiraplot(einstein, spiral_turns = 40, spiral_res = .x, aspect = "portrait")) %>% 
  patchwork::wrap_plots()
