Good discussions today, folks. Impressive breadth and depth of focus.

+1 on watching Brett Victor's stuff: he makes really nice things (like
tangle!) and makes you feel good about being in this technology game that
sometimes just makes me sad.

I did get to a 0.0.1 release of the ipython-blockly stuff here:


The setup is a little fiddly, but I got one cell on the page, generating
code which could then be run. Whew! It uses the `%load_ext`, and a new
metadata namespace (blockly). Right now, it just uses a sub-key `xml`: I
don't know what else could show up there, eventually.

By the by: is there a JSON schema for the notebook versions? I did some
work on that for cdnjs: i found them annoying to build, but useful from a
testing perspective (we were looking at `package.json`s for all the stuff
in the cdn). Perhaps we can use them as part of the "contract" for writing
to notebook on the JS side? or the whatever side, i guess: there are
implementations in most environments.

I look forward to spending some more time on it soon, but am going to be
Not Coding tomorrow :)
