3 column Grid of enabled themes... script included

So I wanted to show some themes to clients that just want to use a free theme and wanted an easier way to look through the themes so I came up with this:

<?php

$themes = list_themes($refresh = FALSE);

echo "<table>";

foreach ($themes as $name => $object) {

if ($object->status == 1) {
$name = $object->name;
$info = $object->info;
$screenshot = $info['screenshot'];



     // make a new if the remainder of $i divided by 3 == 0
     if($i % 3 == 0)
     {
          echo "<tr>";
     }            
            
     echo "<td width=125><strong>$name</strong><br/><a href='http://YOURSITE.com/node?theme=$name'><img src='http://YOURSITE.com/$screenshot'/></a> <br/><br/></td>\n";
            
     // add an extra <td></td> if there are not enough columns to complete the table
     // only test if $i is on the last item of the array
     if($i == ($count - 1))
     {
          // keep adding blank cells till it's at the end
          while(($i + 1) % 3 != 0)
          {
               echo "<td>&nbsp;</td>\n";
               $i++;
          }                
     }            
            
     // end table row if the remainder of $i+1 divided by 3 is 0
     if(($i + 1) % 3 == 0)
     {                
          echo "</tr>";
     }

     $i++;
  }
}


echo "</table>"; 



?>

Thought this might be something that could be added to switchtheme. Or someone can use it just like I did and just through it in a node.
