As you can see this looks beautiful but they were so easy to make :) You actually use plastic wrap to make this. Just lay your filling on the piece of wrap, then add some rice. Pack the corners of the wrap together and twirl the plastic into a ball :) Since Anna posted a nifty tutorial with good looking pictures on this recipe, I invite you to take a look over there for the recipe.
I didn't take pictures from all the sushi I made, but next to salmon I also had avocado, salmon and avocado (see back of the picture), kiwi and cream cheese (a very nice vegetarian sushi combination that I thought of myself) and scrambled tamago. The latter was in the tutorial as well, but for me it didn't work at all. So with those I made just normal filled onigiri.
