Hi Richard & Bill

Speaking about tesselations on the computer, you might want to look at
the following short program:

=====================
to do :size :level
if :level<1[stop]
repeat 6[shape rt 60]
end

to shape
fd :size
rt 180
do :size :level-1
rt 180
end
=====================

To run it for the first time clear the screen and say:

        DO 16 3

Watch the difference between executing with SHOWTURTLE and HIDETURTLE.

Now suggest to your students to explore what is the 16 and what is the
3.

Figuring out that, ask your student to position the FD :SIZE line in
different places inside SHAPE.

Also suggest adding a second FD :SIZE in different places inside SHAPE,
and watch the effect.


etc, etc,  The sky is the limit (and the imagination, of course).

Regards,

[[Yehuda]]
