How about this for incestuous: a Flems of a HN reader, written in Mithril: http://yep.it/ckcpfi

This is great! I can see myself using this a lot. :)

Latest chrome on Android:

ReferenceError: ohnoAnError is not defined

at setTimeout (.js:14:8)

I don't have an android phone at hand, but the error is supposed to be part of the demo. If it appears in the UI (below the code) it is normal. You can click the "at (.js:14:8)" link, you'll get the cursor on the problem line.

I think that's deliberate.

This looks very interesting. Is the code on github ? and if not what's the reason ?

Thanks for checking it out. Yeah, I'll put the code on github for the Flems module during the weekend. I think the intro might have been a bit confusing as there's actually 2 parts to this.

Flems the module: A "js webapp / module" named Flems, which is a Web sandbox/playground that can easily be customized through options & embedded on any site (think programatically setting up playgrounds for example code in documentation etc.).

Flems.io the website: Then there's Flems.io which was launched here, that is a website using the Flems module, and on top of that puts all the state inside the URL. This allows for easy sharing, forking & editing of code examples.

Hope that clears it up a bit

Don't know if it might make sense to do another Show HN for the module once it's up on github?

Yeah, I think it's worth a repost. It's a different use case than it just being another jsfiddle/codepen/jsbin alternative.
