Author here and brand new to Layervault! I was wondering where all the traffic was coming from...
Happy to answer any questions about this. Here's the blog post on it: http://scotch.io/bar-talk/building-full-screen-css3-menus-with-tons-of-creative-demos.
Lastly, you guys can see a non insane and more practical use case that I made here: http://wideeyecreative.com. Making that sparked me to make the demo article.
Great works, congrats! :)
Nice collection, but I prefer hamburgler.js :P
