Spectro Gallery :  Review by Waldemar Januszczak of The Guardian 1980.

Mr. Duffy's Art Games prey, somewhat artistically, on your combative spirit. The aim is to strive towards a work of art by working within a basic set of rules. There are time limits and prescribed materials, subjects and tools to decide upon. Who, after all, is going to make the first tense move when confronted by emptiness? Somehow you feel that most of the rules are there to be waived.  For the Art Game provides fascinating insights into the decision-making process, a visual dialogue as the artist calls it. There are no winners and no losers, only those who say too much, who don't know when to stop making marks on the walls, involving new materials or stretching wires across the gallery which is itself the board; an eye for the significant gesture is the most desirable skill.  At the moment, the gallery looks like a timber yard. The artist is playing against himself and digging deeply into his reserves of schizophrenia. His chess player's mind reveals itself more readily in the details, in the individual decisions, than in the cluttered room as a whole. He is also playing two games at once, obviously trying to relate the upstairs and downstairs galleries.  It is one of the principal joys of the Art Games that by the time you read this the gallery will have undergone several facelifts.
