Fernando's example appears to come directly from minrk's repository on git hub. The code is include there in full, although the documentation is rather thin.
I was able to get this running on my Windows 7 PC using IPython 2.0 and executing the following commands from a command window:
git clone https://github.com/minrk/singlecell.git
cd singlecell
python singlecell.py
These commands start a Tornado server at http://127.0.0.1:8000
. Open the application in a browser by typing that URL in the address address bar. I saw exactly what Fernando showed on screen in his demo.
I hope that helps - you should be able to figure it out in detail by studying the code.
