Hello listeners,
in a project on our university(FU-Berlin), we visualize the recent changes on the major Wikipedia’s (related to language).  It’s called Pediameter.

If you’re interested, you can have a look at our project on http://l3q.de/pediameter/ .
It’s supported on Windows, Linux and MacOSX.

Greets,

Lukas Benedix and Jens Hantke.
