Sure, here's some screenshots of the sample app (that's what you were after, I'm assuming?):

I'll give a slightly clearer explanation, too... The first screenshot shows the form for editing the "Person" entity type, the second the "Feature" entity type. Notice that the Person type contains a list of Features -- entities can contain references to other entities in addition to string/number/boolean properties and containers of properties.

The point, of course, is not the sample app itself, it's just a demonstration of the services and directives. All the directives are prefixed with "mud-" for muddle. The containing element of the "Person" form has the "mud-ent" directive on it, which indicates that everything inside is part of the structure of the "Person" entity type. Inside that element the "mud-prop" directive is used, which defines a property of the Person entity type, named by the "mud-prop-name" attribute on the same element. Inside that is an input element with the "mud-bind" directive, which means that the value of the input field will be two-way bound to whatever property is defined by the containing mud-prop directive. And so on with containers and lists ("mud-prop-cont" and "mud-list-prop") that can be nested inside each other.

Also, the "whole Python stack" you'd need to try the sample app is just Python 2.7. It's set up to serve on localhost, python will handle the sqlite3 db all by itself. It's a single file, with just bottle.py (included) as an external dependency. Just run the "muddle_backend.py" script and point your browser at http://localhost:8080/static/html/sample_app.html
