     @geoffl another way to get more points is, for each calculation, use it to plot a 4x4 block of pixels (covering all 16 thresholds in the dither pattern). I wasn't sure if that's what your original did since the pixels look fatter - I haven't tried to decode how it works

     @bbcmicrobot @DazedAndDiffused it struck me thinking about your image-where illumination is based on depth-that with an ordered dither you wouldn't need to decide which surface is in the foreground, and I felt that was worth coding up
