Previo - Práctica 7

A continuación se presenta el código el cual despliega, en la ventana principal, una fractal de tipo Sierpinski: con un clic izquierdo, imprime las coordenadas en las que está el Mouse y abre una ventana la cual centra dichas coordenadas y redibuja la fractal a partir de ellas; un clic derecho sobre dicha ventana la cierra. Un clic derecho sobre la ventana principal abre otra en la cual aparece el humanoide previamente hecho animado y un clic derecho sobre dicha ventana la cierra. Oprimiendo la tecla ESC, en cualquier ventana, termina el programa.
