Design a modern t-shirt graphic featuring an abstract geometric pattern with bold, vibrant colors. The design should include a series of interlocking triangles and circles in a dynamic, asymmetrical layout. Incorporate gradients and shading to create a sense of depth and movement. The background should be a solid color or subtle texture to keep the focus on the geometric shapes. Use a minimalistic color palette with a few contrasting colors to ensure the design is striking yet wearable. The medium should be digital illustration with clean lines and smooth gradients.
