Hi Ron, thanks for this.

Look great. It’s such interesting material in the rebus of ideas and images. i.e. both visually and ideationally – the business for me will be to put it to work in a way that finds a gap and nudges the field along. This forum / platform is nice for the assembly and the interplay.
Have you read Barbara Maria Stafford’s Visual Analogy: Consciousness as the Art of Connecting? You may find it useful / relevant / interesting. J.Hillis Miller’s Illustration is v relevant to your area here too.
Also: W.J.T. Mitchell’s Picture Theory. Also his Iconology: Image, Text, Ideology.
I particularly liked your whimsical looks at line with that slippage of indexical marking versus agreed conventional coding – i.e. the agreed idea that one thing might stand (in) for another – and the seemingly unconscious translation of one thing for another. It seems to me that there are several things going on in these areas you are looking at / into :). It will be interesting to see how you might categorise them and then put them to the test as it were. cheers, Patrick
