Internet makes you available lots of PowerPoint templates of varied categories on different topics. Most common categories are business, education, maps, animated, medical etc. Animated ppt templates are just awesome. They catch the interest of the audience and especially in case of medical templates it plays a very important role.

It's probably something higher.
