You could try them over easy, which is similar to sunny side up as they are still runny, just slightly more cooked.
Over medium is another, the yolk has a more thicker consistency, and the whites are cooked all the way through.
You can always mix up a couple of eggs in a bowl, add your favorite seasonings to the mix and some cheese, then add it to a pan and scramble them up or make an omelette. Everything with cheese is awesome!
If you love sunny side up, you could take it up a notch. Take a circle cookie cutter and cut out a circle in the middle of your favorite bread. Place it on a greased frying pan, then crack the egg inside the hole. Cook it like you would your normal sunny up eggs and enjoy.
