This was an attempt at the Artist Challenge involving Charles Blackman. The image it was responding to was called "Fern garden No.2" : https://www.wikiart.org/en/charles-blackman/fern-garden-no-2
The fungi my cat was contemplating did not really seem to fit the bill?!
@4rky Thanks 4rky - this started out as a great concept!- LOL - but I don't think it ever actually did what I wanted. It's nice to know you thought it worked any way! Many thanks Rob
