A simple spiral can make fantastic patterns. Change "start", "limit", "angle" and "colour", or press "Random" to see a new pattern. If it hits the side when drawing then the spiral is scaled smaller and smaller until it fits. Click anywhere to start drawing where you clicked. Press space to start drawing again at the last click. That way you can make a pattern fit in the space without being too small. Press "r" to reset the scaling. If you change any of the spiral settings it resets scaling. If "colour" is even then colour is related to position on the spiral (looks like a flower); if odd it's related to position in the space (looks like a rainbow). If you click on a slider to one side of the knob it will adjust the number by 1. That way you can get all the numbers from 1-100.
