To save myself the trouble of having to copy and past massive amounts of code, I'm going to have you start by grabbing the code from over there, and following their directions. You can compile your layer if you want, it won't harm anything, but your subject line won't match anything you already have. What you need to do to make it blend in right and pick up your formatting from your entries is replace everything from "#### Print the tag cloud in an entry-like post ####" down with:
<div class="post-asset asset">
<h2 class="asset-name page-header2">
I am still rather awkward with digging through layers to find the information I need, so there is a chance that there could be a better way to fix the part I had to change. If anyone sees a better way to do this, please comment and I'll update the entry to include the new information. Thanks to the s2flexisquares community for the original tutorial.
