The new Apple Pencil site has an above the fold introductory element where it says "Its only a ... pencil/scalpel/note-taker..." and this scrolls like a slot machine. What is this effect called? I've seen different implementations of this on different websites but could never really figure out what its called.
Like I said in a comment to the answer that was chosen as the right one, I think it is a confusion. "Word real" it is just a random name for the class. It is just an animation there, using a translate3d() CSS function.
I think a suggestive name could be "3D Scrolling Text in CSS3". A similar effect is used in this example that simulates the Star Wars opening crawl.
