GHe � n d S( s� turtle-example-suite:
tdemo_bytedesign.py
An example adapted from the example-suite
of PythonCard's turtle graphcis.
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.
