Latest experiment by Codrops consists of a small set of block reveal effects uncovering content of any kind in a schematic box look.

On the demo page you can also find nice ready-made examples for revealing menus, modals, forms, etc. This approach takes advantages of scrollMonitor (a simple API to monitor elements as you scroll) and Flexbox and 3D Transforms, so only latest browser versions are supported.
