Without gravity, pages float away.
We searched the whole station: this one slipped out through the hatch.

Zero gravity 404
The 4, 0 and 4 drift at their own pace as station debris floats past, with depth that follows the mouse.

Where to use it
Floating numbers feel light and a bit silly, which is exactly the mood you want when someone has just hit a dead link. It takes the blame off the visitor. A product studio, a mobile app or an online shop with a playful brand can use this zero gravity 404 page without it looking out of place.
Violet is the default, but the page reads well with almost any accent, so match it to your main button. Slow the speed down a touch if the floating distracts from the text; the button back is what really matters here.
