Depending on what you exactly want to do you might have different way of doing it.

The first thing you can do is use display protocol (see docs/example/notebook/display_protocol.ipynb) to define html/latex/json representation for object.

other example

Near the end, you have a youtube video python object which representation is an embedded youtube player.

> To illustrate my use-case, here is a notebook  that I created to teach python to 10 yr old kids. To make it more interesting or engaging, I combine rich text, image,  video with code. In this example, I used HTML() to embed a javascript clock at the beginning. But how would one do the same in python?

The other thing we are working on are json plugin
https://github.com/ipython/ipython/pull/2518

have a look at http://vimeo.com/channels/pydata/53051817
for demo.

> If teachers and students can perform virtual experiment, at the same time, do calculations in math/physics via sympy and write a lab report, all within the IPython notebook, it would be a huge boost to our education.

You should be able to do the same and use a custom _repr_html_ to display this form python.

I think the introduction notebook in /docs/example/notebooks/ are a good start to see what could be done. 


also, you can share static version of your notebook through nbviewer.ipython.org.

here is what it looks for yours.
