The IE6 Demoscene

There's an active community of people in the demoscene writing code for long-"obsolete" platforms like C64, Atari, NES, etc. These platforms are slow, quirky, and relatively limited, yet they can do all these amazing things with them.

Seeing all these HTML5 "new features" demos, the thought occurred to me: what can we do with a more limited browser? Not something really limited like Lynx, but something still considered obsolete yet maybe more powerful than most people would think. How about IE6? It has JavaScript so you can write programs in it, lots of undocumented/buggy behaviour, and relatively slow, so could be compared to a C64 in some ways. (Lynx would be like a 4004.) What sort of things can you do with it? Should there be a demoscene category "Platform: IE6"?

Discuss.

Objective: Allow the user to play the audio of Act one, Scene one of World of the Fourth Chánnel : The Musical. User should be able to get access to the audio regardless whether they use Firefox, IE, emacs or a mail daemon that fetches the webpage (that's you, rms). Easiest playback should be available first, then last.

here's my solution- in a pastebin because shii_tchan eats my HTML posts for breakfast and then calls me a spambot, possibly because I mentioned the !!UNMENTIONABLE THINGS!!

Stunning!

I don't like this X-or-Y-or-Z solution, you're only ever going to handle the cases you think of, and it's shitty to handle anything more than one format when storing the audio.

Something like >>54-san's idea would be a lot better.
We could take it further and make any HTML tag that is unknown but contains a src/href attribute to be transformed into a link- or whatever the browser thinks is best. It sees .mp3, it makes a web player (ala HTML5 and the audio tag).

In the real world, people use the X-or-fuck-off standard, which is javascript/jquery for audio, and flash (sometimes with HTML5) for video.
I guess that's the thing, at the end of the day developers want the solution that takes the least amount of time and effort, but displays for the majority of people.
Heck, the only reason HTML5 has been adopted for video is because Apple stopped supporting Flash, and they have a relatively large userbase.
