Large Icon Feature/Plugin?

Is there a plugin that emulates behavior similar to the verge forums?

I’m particularly interested in the large icons at the top, and am looking to emulate that behavior as closely as possible.

You can already do this

By adding images for each category in the category settings.


I know I can add images, but I’m looking for something to actually format them that way as well, nothing seems to be built in. I’m guessing I’ll be diving into a bunch of stylesheets to get that effect vs writing a whole plugin for it (no time to learn ruby and our stack is python :x)
