I put together a wireframe of the Thematic page structure. It was an exercise to better understand the thematic div structure, and I thought I'd share it with you all.
I'd like to change the front end in the future so you can turn on and off css positioning and optional components as well as collapse divs. but for now here it is:

enjoy, and send feedback for improvements. or improve it and send it to me.
