The author's explanation on how it was done: http://www.romancortes.com/blog/how-i-did-the-1kb-christmas-...

It's like watching Bob Ross paint. He makes it look so easy.

I used to have that exact tie.

Great job - but again, I'm reminded how slow Firefox is, in comparison to Chrome. I really hope it gets up to speed in 2011.

For some reason, in Firefox it runs a lot smoother if you constantly move the mouse around over the tree.

Firefox 4 is very fast for this demo.

Jaw-dropping. Time and again I am amazed with what 1K of JS can look like.

Wonderful holiday gift. Merry Christmas.

I think it's both impressive with what people can do in 1k of Javascript because, well, it's Javascript running in a browser, and not given what the rest of the 1k demo space consists of, even in comparison to those for platforms that are older than most js1k participants.

I really wanted to mouse over it and see pine needles or bits of fluff fly off. Very impressive.

I just wish I'd known of this comp a bit earlier, so I could have had a crack at it (before Christmas busyness).

this is really good, is it possible to convert this to png?, with out losing any quality? :)

I don't understand your question....

PNG is a lossless format. The JS code doesn't use vectors for this, it has its own images.... Anyway, if this is what you wanted, here you go: http://grab.by/grabs/9be42370650b27bbf3ae37169bca9243.png

well done.
