I hve no idea how this isn't in VCS.  I checked hg and git.  Is it in
an old branch that I deleted before merging or something?  I have
backups from which to restore, but it would be nice to know how I effed
it up in the first place, eh?

<p>Here is an example of Joy code:</p>

<p>It might seem unreadable but with a little familiarity it becomes just as
legible as any other notation. Some layout helps:</p>
<div class="highlight-default notranslate"><div class="highlight"><pre><span></span>[ [[abs] ii &lt;=]

<p>This function accepts two integers on the stack and increments or
decrements one of them such that the new pair of numbers is the next
coordinate pair in a square spiral (like the kind used to construct an
Ulam Spiral). For more information see <a class="reference internal" href="notebooks/Square_Spiral.html"><span class="doc">Square Spiral Example Joy Code</span></a></p>
