See the Pen Rollers! (infinitely unwrapping prisms; 3D, pure CSS) by Ana Tudor (@thebabydino) on CodePen.
I don’t usually post cool coding things that I find around the web because for the most part, I’m pretty sure the audience here doesn’t care too much. But this is too mesmerizing to watch, so I figured why not. (Also, it’s my blog, and I don’t really care).
It has no real world uses on any website I can think of, it’s more of a proof of concept then anything else, but that doesn’t make it any less impressive in my book.
