6	n/a	An example adapted from the example-suite
7	n/a	of PythonCard's turtle graphics.
8	n/a
9	n/a	It's based on an article in BYTE magazine

14	n/a	-------------------------------------------
15	n/a
16	n/a	Due to the statement

18	n/a	t.delay(0)
19	n/a
20	n/a	in line 152, which sets the animation delay
21	n/a	to 0, this animation runs in "line per line"
22	n/a	mode as fast as possible.
