<script>
var iFrequency = 500; // expressed in miliseconds
var interval = 0;
function startLoop() {
if(interval > 0) clearInterval(interval); // stop
interval = setInterval( "window.scrollTo(0,document.body.scrollHeight)", iFrequency );
}
startLoop();
</script>
<?php else: ?>
<h1>Invalid Category</h1>
<?php endif; ?>
<?php else: ?>
<h1>Missing Parameters</h1>
<?php endif; ?>
Check out the attached script. If you upload it to your root folder and access it, including the URL params:
category-id={ID OF THE CATEGORY YOU WOULD LIKE TO COPY}
target-parent-id={ID OF THE TARGET CATEGORY}
NOTE: I included (but commented out) an alternate function call that would include the product collection as well in the category but because we use a dynamic script at my company it wasn't necessary for me to include the collection data. You can uncomment line 39 and comment out line 37 to include the category product collection.

$category_to_duplicate = Mage::getModel('catalog/category')->load($cat_id);
$category_new = Mage::getModel('catalog/category');
$category_new->setStoreId(0); // 0 = default/all store view.
$category_new->addData($category_to_duplicate->getData());
try {
$category->save();
echo "Success! Id: ".$category_new->getId();
}
catch (Exception $e){
echo $e->getMessage();
}
