In a slideshow, you generally navigate through slides in a linear order. What if the slides were arranged in 3 dimensions, so you could move between them in a variety of ways? This project is a demonstration of that idea. Use the left and right arrow keys to go left and right, the up and down arrow keys to go up and down, and the [i] and [o] keys to go in (forward) and out (backward).
Thanks to @happybird123 for the original project. I improved the code to make it easier to add more slides without having to change the code. You can now also make slideshows that aren't cuboids. For example, press I on the first slide oops i accidentally unshared this
