One exercise which we did in the excellent introductory course in art therapy run by the Childrens Therapy Centre and Crawford College, which was on in Smithfield, was to pick a plastic figure from lots of them spread out on a piece of cloth on the floor. I picked a crow. The first image below is a painting of the kind of world a crow would probably like to be in. Lots of flowers, some sea, a bit of rain and no right angles. Crows are supposed to fly in a straight line, so right angles are probably not something they do at all really..
