Simple Python Turtle Graphic and Code: Simple Pampanga Lantern 1
A stylized representation of the star of Bethlehem that guided the three magi to the birthplace of Jesus. Pampanga lanterns are elaborately designed with geometric shapes and variedly illuminated with electric lights to create a spectacular display of a sparkling star. They are made in Pampanga, Philippines during the Christmas season.
