I’ll echo TomBo’s comments below about memory overlap. I lost track of which of these circles was which, and after 6 months I’m left with a sense of jaggedy swirly silhouetted shapes that makes me sigh contentedly to recall.
I will also heartily endorse the Clarkian nomenclature for those unable to pronounce the proper names. ‘Gary’ is so much nicer than a soul-less roman numeral.
