Visualization of links between Wikipedia articles

I came across a rather entertaining application, Wikiweb - shows the semantic links between Wiki articles.

This is done in approximately the same way as in the add-on to Firefox, which tracked banner ads.

Available so far only for i-devices. There is a program of 5 bucks.

According to the developers, they donate part of the proceeds from the sale of the application to the Wikimedia Foundation. Project
