#2I've been working on this for a couple weeks, attempting to get it looking perfect and get it to 1kb. It's going to be going on stage at http://solskogen.no/ shortly, so I figured now is the perfect time to post.
As far as I know, this is the first ever case of a self-extracting PNG -- the file is a PNG that first is interpreted as HTML, which then unpacks the compressed code within the PNG to start the second stage. I plan to write a blog post about how I got the size down as far as it is, but feel free to ask any questions you may have, as I'd love to see this technique spread!
Edit: Requires Chrome and Firefox -- has been tested heavily on Windows and OS X, but this will eat your CPU and GPU alive.

#3Can you give us a few details of what you did? This makes my i7 cry.
Edit: Just saw your explanation. Cool - thanks!

Pretty cool hack! I'm looking forward to the blog post.
It doesn't seem to eat my processor too much. In Chrome with AMD processor it's sitting at about 25% CPU usage.

It isn't too be on the CPU for most people, but for some reason it's eating a massive chunk of CPU-time for some people -- seems to be only in the latest Firefox nightlies, but i'm not seeing it here, so I'm unsure of what it could be.

Do you have a quad core CPU by chance? 25% is the max that a single-threaded process would use. (Someone please correct me if this is wrong, but at least this is the behavior I've observed.)
That being said, this uses only 10-12% CPU on my quad-core machine.

#7Very neat. I'm happy to see that the demo scene magic still exists. I thought the days of seeing an animated ray traced scene from a 256 byte EXE were over.
This runs fluidly on my Chrome/Sandy Bridge/Ubuntu setup.

If it's 1k, then it's a serious contender.

Ah, I guess I should have specified. It's a Phenom 8750 (triple core.)

It depends on what you use to report CPU usage. Many monitoring tools stick with 100%/core, but some normalize it.
