In this demo, I draw a field of flowers by drawing the same flower 144 times. The flower is composed of six circular petals and a yellow circle in the center. The color of the flower is selected randomly. The flowers are drawn on top of a green rectangular field and a blue rectangular sky. The sun is a circle filled by a radial gradient. I animate the cloud to float lazily across the sky by erasing and redrawing it every 50 milliseconds (twenty times a second). Learn more.
