jimt,
Obfu is not my thing, but I do love interesting math problems. The following is more of a golf (156) than an obfu:
use Math::Pari 'lcm';my($n,$d)=split/\//,shift;sub p{print"1/$_[0] "}w
+hile(1){my
$u=int$d/$n+1;p$u;my $l=lcm$d,$u;$n=$n*$l/$d-$l/$u;$d=$l;p($d),die$/if
+$n==1}
Golfing with strictures and warnings is a handicap so (146):
($n,$d)=split/\//,shift;sub p{print"1/$_[0] "}while(1){use Math::Pari
lcm;$u=int$d/$n+1;p$u;$l=lcm$d,$u;$n=$n*$l/$d-$l/$u;$d=$l;p($d),die$/i
+f$n==1}
Since I am not a golfer either, anyone interested in the starting code can use it to improve things.

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>
<u> <ul>
-
Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).

are good places to start.
