@errantscience @colm_ryan TBF, this was a hard one to write; & I had to break my rule of getting all the most important stuff in the 1st 125 characters (apparently some text readers have auto-cutoffs there). It’s easy to describe things people have seen before (“Bird perched on the back of a sheep out in a sunny pasture. Bird is black, sheep is white, grass is green, sky is blue”). But no one’s seen a 3D Venn diagram before, so they don’t know how to expect one to look.
