Saw this fun painting and wanted to do something similar.[br]Francisco Sobrino (Spanish, 1932-2014), [i]Untitled[/i], 1959. Gouache on paper, 47 x 47 cm[br][br]The sectors are randomized when not using functions.[br][br]On the turns setting, some of them are rotated 90 degrees. [br][br]On the functions setting, it uses the fractional part of the function value on the rows (y, n of them) and columns (x, m of them) to determine how much of the first quadrant is filled in.
