This geometric abstract composition features interlocking curved and straight lines creating a complex system of modular shapes. The color palette consists of bold primary colors - red, yellow, and blue - along with black, white, and forest green. Large sweeping curves in black and white dominate the center, while smaller rectangular and triangular elements fill the surrounding space. Piano key-like patterns appear in multiple sections, suggesting a musical or rhythmic quality. Small circular dots in red and black punctuate the composition at regular intervals. The overall design creates a sense of movement and interconnectedness, with each section flowing into the next through shared lines and shapes. The structured yet dynamic arrangement reflects the "modular structures" referenced in the title, with distinct sections that fit together like pieces of a complex puzzle.
