Hippie-Modern T-Shirt Design with Psychedelic Patterns and Bold Text

Create a back t-shirt design inside a rectangular or square box with a hippie-modern aesthetic. The box should have a bold, colorful, and intricate design with abstract, psychedelic patterns. Include elements like swirling shapes, cosmic eyes, floral patterns, or trippy geometric lines. Use a vibrant color palette with neon pink, electric blue, golden yellow, and hints of black for contrast. Overlay the design with strong, eye-catching text in a bold, stylized font that says “WILD SOUL,” “LOST & FOUND,” or “REBEL SPIRIT.” The text should slightly overlap the box edges for a striking effect. Add a subtle grunge or distressed texture inside the box for a rugged, edgy vibe.
