Looks interesting but it took me a minute to realize that you don't actually need to register to see the site's content. For some reason, the page ignores keyboard navigation (page down/up, arrow keys down/up, space bar) in Firefox (only) so, on my laptop, the page looks like it has no content except the register button.

Also, the page uses a background image blur that is supported by Firefox and Chrome, but not IE or Edge.
