It works well with geometric spell construction," she gestures indicatively at the layout of chess pieces and masking tape on the floor, "which I've always found a very intuitive medium to work with. And it worked the first time I tried it and has been working reliably since, which is more than I can say for some of my experiments with more freeform stuff."
