jpayne@69 3
jpayne@69 4 tdemo_bytedesign.py
jpayne@69 5
jpayne@69 6 An example adapted from the example-suite
jpayne@69 7 of PythonCard's turtle graphics.
jpayne@69 8
jpayne@69 9 It's based on an article in BYTE magazine
jpayne@69 10 Problem Solving with Logo: Using Turtle
jpayne@69 11 Graphics to Redraw a Design
jpayne@69 12 November 1982, p. 118 - 134

jpayne@69 14 -------------------------------------------
jpayne@69 15
jpayne@69 16 Due to the statement
jpayne@69 17
jpayne@69 18 t.delay(0)
jpayne@69 19
jpayne@69 20 in line 152, which sets the animation delay
jpayne@69 21 to 0, this animation runs in "line per line"
jpayne@69 22 mode as fast as possible.
