This GeoGebra project shows a flower with rotating petals which change their colors overtime. The stem and pestle were created using basic shapes and lines. The petals were created using the sequence command. The colors of the petals change overtime due to the sliders a, b and c. Each slider uses the RGB color system. For example, in slider a R is 1 while G and B are 0. There is also a fourth slider which rotates the petals around the pestle in both directions. In conclusion, this is a very simple and fun project.
