Diller's geometry seems more spirited and less redundant than Albers's--more Malevichean. One dark square with various agitated rectangles in it seems to recall Malevich's aerodynamic phase, and one blue square with a white-and-yellow rectangular strip above brings the final puritan, transcendental phase of Supremati to mind. If Diller is more playful than Albers, however, he's more nervous than Malevich.
Diller's geometry is more spirited and less repetitive than Albers', with a stronger resemblance to Malevich's work. One dark square containing agitated rectangles evokes Malevich's aerodynamic phase, while one blue square with a white-and-yellow rectangular strip above suggests the final puritanical, transcendental phase of Supremati. While Diller is more playful than Albers, he is also more nervous than Malevich.
