codemirror (e.g., the sage cell, samuel's port of the notebook,
William's salvus project, the IPython notebook, etc.)
Here's a very simple proof-of-concept:

In the lower right pane, highlight an integer and press "Insert Widget".
Then you can change the integer by clicking on the buttons.
* live images in the input code, automatically uploaded to the server,
drag and drop from your browser, or even just an image editor so you can
draw your image
* live mathjax-based equation editors
* matrix/table data editors
* a d3-based live graph editor (i.e., vertices and edges), right in the
and a huge number of other possibilities.
Anyways, I thought people here would be interested.
You'll notice that the text content has weird unicode characters in it
delimiting the boundaries of the widget. The live widgets can put just
single values in the text, but they can also embed json-encoded
messages. When the cell is interpreted for evaluation, the unicode
widget delimiters can be stripped out, the message decoded and relevant
python code generated, and then the widget message replaced with the
generated python code.
