The JS1K is a demo-competition for creating cute, interesting or impressive interactive things in web browsers with JavaScript.

The catch is that anything entrants create must total no more than 1kb in size.

1K! That is sooo tiny. You couldn’t even fit one of Marcus Fenix’s meticulously-manicured fingernails in 1kb of data. 1kb! It makes David Braben’s space-trading classic Elite (created in 22kb) look positively indulgent.

This year’s competition is now closed and you can see some of the entrants and winners here, from a simplistic Minecraft-inspired sandboxing block game with an infinite map containing snowy mountains, grassy slopes, seas and waves, through to my personal favourite, Paul Sonnentag’s meatball puzzle game Overflow.

Hop along to the main page to see the brightest and the best sub-1kb entrants and where, if you can read code, you’ll also be able to see how they did it. Fascinating stuff.
