+
+An example adapted from the example-suite
+of PythonCard's turtle graphics.
+
+It's based on an article in BYTE magazine
+Problem Solving with Logo: Using Turtle
+Graphics to Redraw a Design
+November 1982, p. 118 - 134
+
+-------------------------------------------
+
+Due to the statement
+
+t.delay(0)
+
+in line 152, which sets the animation delay
+to 0, this animation runs in "line per line"
+mode as fast as possible.
