As an experiment I decided to squash the circular motif in one of the small watercolours – this deletes the reference to the idea of the Petri dish (a reference that makes very little sense anyway in the context of images drawn from electron microscopy though I guess? that the lens is circular) but provides another formal constraint.  How I’ll make a support for these if I decide to make larger paintings I can’t hazard a guess as yet.  In this work I’m using an original source that I never noted down so the referents in the work are lost altogether but again this is of no interest to me in any event!
