An abstract, generative composition uses two SVG masks to reveal intersecting rectangular grids. The first mask, defined with a `<rect>`, limits a series of horizontal strips to a central vertical band, while the second mask combines a white background with a black `<rect>` to define a complementary area for vertical strips. The resulting visual, created with 100 elements per axis, produces a woven or striped pattern using only white and black. The code demonstrates dynamic SVG creation and mask application without any external libraries.
