Experiments in Inheritance - a screencast

This is a short screencast I made to replace the video made at my London Perl Workshop presentation. It did not make the list eventually - but I still think it might be interesting: http://warszawa.pm.org/WebNanoInheritance.mpeg. It is my first screencast ever made - please comment.

The main idea presented there is about solving the "give mi an application like this one but ..." problem, illustrated by making a blog engine that inherits from Nblog, but extends it and overrides some of it's elements.
