I have created hundreds of presentation title slides, by far my favorite slide from my freshmen year of college. Before I even began to explore digital art or anything that would be considered "visual art representations" I just enjoyed simple somewhat colorful imagery  that could catch the someone's attention. The program used the title slide was Apple Keynote, while my title slides have more extravagant elements in them like 3D imagery, gifs, etc. they still follow my basic principle of having clean and eye catching introductions.
