fun for 2014

Christmas - the time of the stars: Just a few you will find in this "Christmas-New Year's Card". 2014 may bring you many colorful-creative stars. Start to drive with full steam!
Use the sliders to the right to set different stars as a template: • draw the given star as precisely as possible by drawing your "green star" with more or fewer vertices (points), • determining how many "corners" (points) should be skipped when drawing the green sections, • increasing or decreasing the green drawing,  • rotate the green star around the center point.
