+I made <a href="http://media.unpythonic.net/sufograph/">this little graphical
+toy</a> last month.  I had intended to put a few finishing touches on it before
+blogging about it, but instead it has languished.
+
+<p>Enter a few numbers, press &quot;update&quot; and get a geometric pattern.
+
+<p>Requires a browser that supports svg, which must be most of them by now.  I
+tested on Firefox and Chrome.
+
+<p>(Updated to actually link to the toy)
