These are really awesome - a very big well done to the author.
Only this morning I was thinking of how to implement a few of these types of interactions for a web app I'm developing - I actually might adapt some of the source code for my uses (assuming that's allowed under the License?).
If you're still working on a syntax for this, maybe you'll want to have a look at uilang or uiscript (both on Github) or Grid Style Sheets (http://gridstylesheets.org/).
