This is the page I was looking for this morning. All the wonderful
plays on the words "Turing" and things which come from "<a
href="http://en.wikipedia.org/wiki/Turtle_graphics">Turtle
Graphics</a>" and "<a href="http://en.wikipedia.org/wiki/Graftal">Graftal</a>"
"<a href="http://en.wikipedia.org/wiki/Koch_snowflake">Snowflakes</a>"
(space-filling curves which can operate like<br>
a Turning Turtle). [See also:

<blockquote type="cite">In keeping with his topic of programed
paths, <a
href="http://www.ifp.illinois.edu/%7Esdickson/G4G8/G4G8_Dickson_Notes.html">Martin
Gardner</a>'s original column
discussed the <a href="http://el.media.mit.edu/logo-foundation/">Logo</a>
language. I highly recommend <a
href="http://ccl.northwestern.edu/netlogo/">NetLogo</a>, and the
chapter about Logo in <a
href="http://www.wolfram.com/products/explorer/topics/turtle.html">The
Mathematical
Explorer</a>.<br>
</blockquote>
Logo uses Turtle Graphics. See also the MIT Lego Logo Lab<br>

I like the one which constructs a Golden Rectangle.<br>
These can be mechanized by using a purely mechanical Flip-Dot
display as the 2-D Turing tape.<br>
