QUIZ NIGHT

I had a very early start for a shoot in the West End today so it's only now that I can post this photo which I took at The Photographers' Gallery last night.  I was there for a networking event with other photographers but before that I visited the Saul Leiter retrospective on my own, as well as an exhibition by Brazilian artist Rosângela Rennó of projections of vintage slides using 20 salvaged analogue projectors (half of which had unfortunately broken down).  The words on this wall presumably had something to do with the Rennó exhibition but none of the gallery staff I asked seemed to know exactly what.  I was really only interested in finding out because my surname appears in the list of seemingly unassociated words.  Not so much Only Connect as I'm Sorry I Haven't a Clue.  Any Answers anyone?
