They have several of these landing pages, you can toggle between them by clicking the "I don't get it" button that floats in the bottom right or by clicking the logo.
I'm not going to lie, just from what they have on their several landing pages it looks like a cool project. Bookmarking for future reference and to check if they're still around in 5 years.
Found this one particularly charming. First time I've ever been pleasantly surprised by a mouse-over-background-effect.
Kinda neat hovering the mouse around and watching the little "." move the white part. Unfortunately, they cost me some extra work. I began to realize how many times I have sneezed with the laptop on my lap without cleaning the screen ... I kept seeing dots that weren't there and had to break out the wipes.
