Van Gogh’s flower paintings were intended to be life affirming, representing joy, appreciation of nature and mankind’s love of the divine. In this installation view of Urs Fischer’s piece ‘Denominator’ at Gagosian Gallery, a replica sunflower painting is overlaid with a projection of talking heads sourced from the internet, a juxtaposition geared to suggest that our devotion has shifted to the virtual realm. The painting is part of a recreation of a room in London’s National Gallery, the added heads commenting on how traditional ways of spreading culture have shifted to individuals using on-line platforms. (On view in Chelsea through Oct 15th).
