JS1k

I just know that there is a competition about javascript called JS1k. As the name self-explained, this is about to write a javascript program with 1k only. Unfortunately, when I know this event, the deadline passed. The rules are

1. Create a fancy pancy Javascript demo
2. Submissions may be up to 1k. (And not crash)
3. Externals are strictly forbidden, unlike "some" contests. (Good luck minifying jQuery though!)
4. Must work on current fx, sa, ch and o. (Let's level the playing field)
5. Minification and hacks allowed. (Go nuts)
6. Bonus points if your submission fits in one tweet ;)
7. Last day to submit is 10 September 2010
