The adverts at the top - how do they do that?

I suspect that the module at the top of every mylot page is hand-coded for mylot, but is there anybody who knows differently? Is it something I can find/use/plug in to my webpages at all? It intrigues me. It is obviously picking out subjects from my profile but I like the look of it. I like the styling. Thanking you in anticipation.
