2020 04 not where it was going originally

This was made, largely by removing the main areas of colour, leaving just the fringes around the edges. It is experimental in so far that I haven't tried to make a finished image out of these outlines before. Sometimes you get left with them when you are cutting and copying shapes to place into separate layers, in Photoshop, but normally they get deleted as they detract from the sharp outlines of the primary patterns.
