HTML quine
This is my really naive quine. It can hold a little html. I'm not sure it exactly fits the definition, but you can select all and paste this into a new html file in notepad, and it basically makes the same thing.
I'm sure someone who knew javascript could do this in like two lines and make it hold any kind & amount of HTML. Feel free and share me your code at judgmentalist@gmail.com.
P.S.: It's got a little <noscript> section at the end so that the text still shows in a non-javascript browser. If you don't see blechy gray code around this text, then you probably aren't running the quine.
P.P.S. If I get my act together, I'll make a quine generator quine that will produce one of these things given any HTML, and will have a little AJAXy text box that you can pop up which will let you edit the HTML without writing the crud I have to write when I edit these things. If you see what I mean.
