Lissajous with sliders 

This is to draw Lissajous figures with sliders to allow exploration of the effect of varying the horizontal and vertical frequency.

Size can also be adjusted so that the finiished design can fit the embroidery hoop being used.

My contribution is simply to add more comments and to create a worksheet.
