300g sushi rice
300ml water
1 TBS Rice Vinegar
1 TBS sugar
2 sheets of seaweed for sushi

It is very important that this is cooked in an open pot, or it will burn and cook incorrectly.

Cook the rice with the sugar and vinegar for 15 minutes on medium heat.

Remove from the heat and allow to cool.

Once the rice is completely cooled, you can shape with your hands, or use forms to make shapes.

Cut the seaweed wraps as you like, to put on the onigiri so it is easier to eat with the hands. This is great for bento boxes, or for dinner meals.

We had some tonight with Teriyaki chicken.

Here are several photos from Google on how you can make yours look.

Here is a better instructional than mine (I was translating from a German site)
