Interlocking yin yang symbols repeat across a bold black and white checkerboard ground, creating a mesmerizing optical illusion that shifts between figure and ground. The monochromatic palette and geometric precision give the composition a hypnotic, almost kinetic energy that rewards sustained looking. Sewn from a durable canvas-like exterior with a soft lining and made to order, in three sizes up to one that fits a tablet. A catchall for toiletries, art supplies, or small electronics, carrying an independent artist's work instead of a plain zip bag.
