As I said, a lot of the obvious things. And if you're scrolling through the front page without being logged in (i.e., so the default "no mature content" filter is on), there's some really creative stuff being done. I personally like the looks of the RPGv5 (or is the guy up to v6 by now? I forget) model, and plan to use it eventually to create custom portraits of characters in my tabletop roleplay campaigns. (Not running any right now, due to having basically zero free time at the moment, but eventually my current situation will change and I'll have the occasional weekend open again).

But for a site sharing code-generation models, it's a very different scenario. I'm curious to see what will happen in that space.
