I don't know why I think of this as the angry pentagram, but I do. It was done some time ago in the large sketchbook (about 10 by 14 inches) and was done with gouache. There is a loosely constructed pentagram and 5 blue dots. Perhaps the fact that there are 5 Moran brothers explains my obsession with pentagrams and pentagons. And the math part, mustn't forget that influence.
