A minimalist abstract design for a t-shirt, featuring fluid, intersecting lines

A minimalist abstract design for a t-shirt, featuring fluid, intersecting lines that create organic shapes and forms. The lines flow gracefully across the design, with subtle gradients and curves that suggest movement and balance. Hints of geometric patterns are woven into the composition, adding structure without overpowering the organic elements. The overall design is clean and harmonious, with a focus on the interplay between the flowing lines and the negative space. No background, only the abstract shapes and lines should be visible, perfect for a modern and sophisticated t-shirt design.
