As someone who spent the last two years of his life helping people learn canvas: Love love love.

These are wonderful, and its especially wonderful that it's open source so others can learn from it. Even more so since there are so few good examples of animation(s) out there right now.

...On the other hand, demos/intros/effects that use a library that is explicitly made for just old-school demos/intros (http://code.google.com/p/codef/) are not as helpful to would-be canvas programmers and artists as it might be otherwise (if the demos/intros were made from scratch and stood alone).

> "PLEASE USE Chrome / Chromium to browse this Website !!"

I use chrome but this line reminds me of "This site best viewed in Netscape Navigator", which is a tad irksome :(

    (more than 300% perf Vs FireFox ;) )

That line reflects people's bad perception about browsers (It's obviously wrong). Only thing that doesn't work using chrome is the music on the home page, speed is the same on both browsers.

It was probably true at the time it was written. Chrome had a clear speed advantage for quite some time.

Hmm... Chrome 21.0.1180.89 Mac OS X 10.7.2 has music on the homepage. Start playing immediately.

It depends on the reason.

Recommending a browser because you are using mark up that only this browser knows is bad.

Recommending a browser because that browser is ahead of all the others in terms of spec support is fine.

Excellent. Now to find some time to recreate the RSI Megademo(1) (Romeo Knight!) and and Scoopex Mental Hangover(2) and I never have to boot up my A500.

Edit: maybe someone here knows/can guess; I'm looking (for a long time) for a cracktro which had a very long musical score which culminated in a Jean Michel Jarre kind of high pitch synthesizer fest. It had (only? I don't remember a scroller or anything else) a 3d starfield which moved back and towards you with the music.

Amazing work!

Minor pet peeve, my favorites are missing;

http://www.youtube.com/watch?v=It-f6CCVtx8 (the low youtube framerate sadly doesn't do it justice)

http://www.youtube.com/watch?v=-5BDh4z5gis (tune...)

http://www.youtube.com/watch?v=wG84cj4rago (NSFW)

IMHO, I didn't like (1) or (2) - but I was very fond of your third (NSFW) link.

However, the demo that first blew me away on the Amiga was Blizzard Crystal Hammer, http://www.youtube.com/watch?v=LXBx6U_JWfQ

That's when I first realised that the Amiga could be like the C64.

I used to be active on the scene (as a demo coder and cracker) - and it's great to see that people still celebrate the old days.

Sweet, haven't seen this site before!

For more nostalgia, a large collection of cracktro remakes in Flash can be found here: http://flashtro.com/

Great demos, thanks. Anyone know how the smooth scrolling is achieved? is there an equivalent of a BitBlt in HTML5 Canvas?

Yes, Canvas has a drawImage method which takes a source image/canvas and draws it on the destination canvas.

This is the only one I remember from back in the Amiga days... the one with the red bouncing balls ... by "Dr Mabuse" http://www.youtube.com/watch?v=2RO5xaP5TSk Not sure if it is on WAB or not, couldn't see it.

WAB and are nothing but thieves, be careful what you use from CODEF because I guarantee NoNameNo the talentless bum has stolen every source he has in CODEF from other people and removed their names and license details.

What are the 'original' libraries/components then?

More info please?

Really, really cool. I just wish the code would be a little cleaner (lots of global variables, using new Array() instead of []), which might serve as a bad practice to people learning Javascript.

What's wrong with []?

Nothing. He's complaining that they used new Array instead of it.

Oh, I thought he meant the other way round, my bad!
