Most people only make sushi rice to shape into onigiri. This is pretty much the sushi rice shaped into a simple shape, mainly triangle. It will usually have a little bit of filling in the middle. An example would be to have some pickled plum, salmon pieces, anything you want really. I find if you don't have any specialised piece of kitchen tool to make it, it's easy to use some plastic wrap, place warm rice in it, add filling in the middle, then roll up the plastic rice.
My friends love to make there own kinds of sushi with the rice, they put a layer of rice down and add layers of other stuff like cucumbers, avocados, sausage, shrimps, etc, and roll it up.
At one point, I had a friend who didn't or couldn't have burger buns at our BBQ. I had some leftover sushi rice. I shaped it into a bun while cold and fried it like a patty! It worked and she loved it!
