Every presentation slide should have a clear organization, and direct the eye. Paintings are a good example. Have a look at this painting by Monet: The garden at Sainte Adresse. It is clearly divided in 3 horizontal bands, has a strong diagonal cutting across, and the flags and steam clouds from the boats  provide energy that leads the eye from left to right.
