I think it would be really cool if there was a way to have mobs look at the camera.

I love taking pictures of a whole lot of things, especially my pets. The thing is, whenever I take selfies with them, they just stare at me like the little goobers that they are, so I was just wondering if there was any way to have mobs look at the camera while you're taking a picture. Maybe with a config option to adjust whether they do this or not, maybe it triggers within a certain distance, maybe only for certain mob types, I dunno, just spit-balling here.

Another, semi-related idea I was thinking about was an item that would be able to set where a mob is looking, so that they could be "posed" for pictures.

This is a good idea. I'll see what I can do.
