A dense checkerboard pattern of black and white squares warps and undulates across the composition, creating the optical illusion of movement and spatial distortion. The repetitive geometry bends and flows as if the flat surface were rippling, producing a hypnotic, vertiginous effect that challenges the viewer's perception of stillness. 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.
