Not sure whether I'm actually going to do this but just curious how y'all would handle it. In the above pen I'm basically moving through 4 quadrants of a square on scroll, and that all works fine. Trying to figure out how I could make it infinite, but it seems like setting body to scroll position 0 doesn't work, unless I'm typing something wrong. Any thoughts?  See the Pen eYeOxZJ by kslaton (@kslaton) on CodePen
