A second body of work refers to vintage "dexterity puzzles". A player tips small glass-covered boxes in an effort to roll tiny ball bearings into holes or through mazes. One never touches the balls nor does one touch these paintings.
These paintings are meant to be the puzzles in themselves – puzzles to be played in the imagination. The challenge for the viewers is, without knowing "the rules", to push the balls into place through sight and thought alone.
