ARTIST RUPERT SLACKSTRIPE, who painted Cirencester beige, has been arrested on charges of simple assault after he attempted to apply spray-paint to five visitors to the Duck Hollow Museum of Art. Through a spokesman, Slackstripe described the charges as “a triumph of philistinism.” The spokesman said that the spray-painting was part of a work of art entitled To the Nth Degree, which requires unwilling participants to make its point. The misdemeanor assault charges represent a significant stylistic departure for Slackstripe, most of whose previous works have been felonies.
