Well, the four of us (her, her kids and me) just sat staring at a smartphone app while it was "painting"... Basically someone was drawing hearts and then colouring them like almost-rainbows and then putting glitter on everything and then removing the excess glitter, shrinking the heart and immediately starting on a new one. Not sure how many such hearts were included but the image with the small ones probably could contain at least 12 of them.
