Brian Clarke’s stained glass screen Blue Computergram features his computergrams, geometric symbols derived from the light-metering displays of Olympus OM System cameras, which he first introduced in his work in the 1980s.

In the 2020 catalogue Brian Clarke: The Art of Light, Paul Greenhalgh describes the work as "a complex exercise in pattern generation." About the the colours and patterns, he adds that these are "creating the effect of conceptual pointillism perhaps, very much in keeping with much of the artist’s oeuvre in painting. The imagery hangs tantalisingly between the natural and artificial, conveying the feeling of a landscape affected by computerisation."

The screen's imagery is derived from Clarke’s 1981 Computergram Paintings series. Clarke had long wished to translate his computergram motifs into stained glass, but could not at the time as the appropriate technology was not yet available.

The screen’s imagery draws on Clarke’s 1981 Computergram Paintings series. This folding screen was produced with an innovative technique that eliminates the lead cames traditionally used to support and join stained glass, allowing the glass to interact freely with light and space. Blue Computergram exists in an edition of 10 unique variants plus 3 artist’s proofs, published by HENI.
