Retrieve a random selection of ChildCategories for the home page
I have been trying to figure out how to retrieve a random selection of child categories using the product/list/random.php as an example. I have two issues. I can not get the select rand() to work for categories and what I really need is the ability to select randomly from all the sub categories at the lowest level. Any help or direction would be appreciated.
I have extended Mage/catalog/block/navigation.php if that helps.
