"Envision a large, complex mandala meticulously crafted using only square-shaped post-it notes. Each post-it is a different vibrant shade, creating a kaleidoscope of colors. The mandala is symmetrical and geometric, formed solely through the arrangement of these square notes. Imagine intricate patterns made up of smaller squares within larger squares, creating a sense of depth and texture. The arrangement of colors should form a harmonious gradient, transitioning smoothly from one hue to another, radiating outwards from the center of the mandala. The background is plain, emphasizing the bright, structured beauty of the post-it note mandala."
