Impressive compression and demoscene craft
From 4 comments
Very 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…
resnamen on HNHey, congrats on finally getting it out there! Saw how much work you poured into it and glad it's finally done. Also, mind-bending implementation.
yan on HNDaeken, you are a graphics/web wizard of the highest order. Congratulations :)

Clever hack that works in a PNG
From 3 comments
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.
robflynn on HNIf it's 1k, then it's a serious contender.
p0nce on HNVery cool! I'd love to read how the PNG hack works. To see if your browser supports webgl, go to http://webglreport.sourceforge.net/ On a pokey mac mini, I get a few frames per…

Objections
Runs very slowly or hogs CPU and GPU, locking up machines
From 4 comments
Just to add another token data point. I have it up full screen at 1920x1200. CPU usage is sitting between 50 and 75% of one core and GPU usage jumps back and forth between 40%…
ktsmith on HNHeh. Screen went black for a while, after which: "Display driver nvlddmkm stopped responding and has successfully recovered." Using an old NVIDIA GeForce 6200 with driver…
tsvk on HN(Repeated) kernel panic on Macbook Air/Chrome I'm afraid.
Emore on HNThis is very cool, but when running it on Chrome 13 beta it was extremely choppy and basically locked up my PC. It took 2 minutes to move my mouse to the "close tab" button.

Blank screen or does not load for many users
From 3 comments
Apologies, but nothing happens when I view it. Running Chrome 12.0.742.122. I see the initial raw PNG splat, but get nothing but a lot of high cpu and a blank browser screen…
geuis on HNIt does not work for me either - blank white screen. Same setup, Mac OS X and Chrome. I do get the canvas when pasting that snippet, though.
nvarsj on HNSame situation as the rest of this thread - I just get cpu usage and a white screen, in Chrome stable/beta/dev. OSX on a MBP, only thing I can think that might be shared with…

More a polyglot than a true self-extracting PNG
From 2 comments
Even so, I think this is more of a Polyglot than a self extracting PNG.
simcop2387 on HNSo, it the header makes it look like a PNG: ``` magister.html: PNG image data, 1242 x 1, 8-bit grayscale, non-interlaced ``` If you look at this in an image viewer, it's as…

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

Questions
Why it fails to load in some browsers and setups
From 2 comments
Only thing I can think of at this point is that you have an extension inserting something into the body before the canvas. While on Magister, drop…
daeken on HNThat's not a JS error. 'S' is a function defined in WebGL, which gets pulled out and names are passed through a regex that filters out certain characters. So it's not getting a…
