A kaleidoscopic fractal tunnel written entirely in GLSL. Space is warped, mirrored into eight segments, then folded into itself again and again, and each layer adds a thin ribbon of neon light. Every pixel is computed on the GPU in real time. Use the sliders to change speed, layer count, warp, glow, and hue: from a precise, glowing mandala to something liquid and alive.
