Artesian sandbox. Get it? (Artesian) water + sand(box) = ... :)
Update May 7, 2012: I'm still struggling with devoting time to Artesian but I am working on it here and there. The project is very much alive, just has painfully slow progress.
This is basically the rough draft of Artesian. I am working iteratively, often adding code only to remove it later when I figure out a better way. Commits are being done periodically but I often have newer code on my laptop. You can grab it from git and play around but please don't write patches without talking to me first. I'd hate to see anyone wasting time making a patch for something I already have fixed on my copy or on code that gets wiped out anyway.
Absolutely do not use this in production. If the number of fatal errors don't scare you away hopefully the fact that I have not done a security check and I don't guarantee a data path, yet, will. :)
