Summary

DescriptionArchimedean spiral.svg	Three 360° turns of a one-arm Archimedean spiral. The spiral is drawn as a series of minimum-error Bézier segments, one for each 45° section of the spiral (24 segments in all). 0°: 0px 45°: 12,5px 90°: 25px 135°: 37,5px 180°: 50px 225°: 62,5px 270°: 75px 315°: 87,5px 360°: 100px
