Very simple tag cloud help please

[treelovinhippie]

hi

I have a bunch of video categories, and I'm trying to make a simple tag cloud of the available categories (with the larger sized category having the most videos in it)

This code already generates a loop of all the categories, I just can't workout how to have this also lookup the number of entries in each category and then spit that out as an array (trying to use this code for the tag cloud: http://www.v-nessa.net/2007/02/12/how-to-make-a-sexy-tag-cloud/)

    /* FIND CATEGORIES */
    if (!is_array($categories = explode("|", $CONF["VIDEO_CATEGORIES"]))) $categories = array();
    foreach($categories as $catName) $categoriesArray[] = array("category.name" => $catName);
    $tpl -> Loop("categories", $categoriesArray);
