From the Moon you can see the whole Earth, but this address is nowhere to be found.

Where to use it
People hit a 404 more often than you think: an old link in a newsletter, a typo, a page you moved after a redesign. This Earthrise scene turns that moment into something calm and pretty. It fits a travel agency, a science museum or an environmental project that wants a 404 error page that still feels on brand.
Paste the 404.html as it is, or tweak the blue accent and lower the speed if you want it more contemplative. Keep the button text short, something like “Back home”, so nobody has to think about where to go next.
