Jajco

Jajco is a joke page at jajc.ooo. Whoever gets the link learns that they have just been "egged", and a counter shows how many people landed here before them. The page is deliberately built like the 90s: a patterned background, a swinging egg and a blinking line.

The Challenge

The joke only works if the page opens instantly, on every phone and from every messenger. The counter also has to count correctly when the link spreads across several servers at once and many people open it at the same moment.

Our Solution

The whole page in one HTML file: the egg, the background pattern and the icon drawn in SVG right in the code
The swinging egg and the blinking line as CSS animations
A PHP counter with a file lock, so simultaneous visits are never lost
An LCD-style counter that disappears when the server does not answer
The jajk.ooo and piw.ooo addresses redirected to jajc.ooo
The same layout on phones and desktops
