First thing that came to mind. I remember in school at least 10 years ago we used it because a teacher liked it. Most of us just used it as a Powerpoint alternative, but a few kids definitely harnessed the extra power available over a generic slideshow. I remember being really impressed at the creative presentations a few people made with it. Fun times.

I remember it being "the future of slideshows" back in 2012, and then the hype died.
