This error page is a pink funfair claw machine with chasing marquee lights, a glass case and a pile of plush bears around a gift box marked 404. Arcade buttons move the claw left and right, the big red button drops it, and whatever it grabs rises halfway before slipping back down.
The controls are real buttons and also respond to the arrow keys, credits count down and refill, and a hidden message tells screen readers how it went. Adjust the yellow accent and point the button to your home page.
