Spot 50

This spot demonstrates how to draw a complex closed shape with epicycles based on the Fourier series. A left mouseclick into the canvas erases the deer drawing. Now You can draw Your own closed shape with the left mouse button down. If You release the mouse button, or if you leave the canvas while drawing, Your drawing is redrawn with epicycles. Save Your drawing with the right mouse button.
