Yesterday I had an e-mail from Helga (Brazil - http://www.slideshare.net/Helga) to make her PPs in my way! The same invitation had Vili (http://www.slideshare.net/vili48).
This is my PPs version; I hope that you will like it!
This is not a competition but a friendly way to build the same subject!
Wishing you all the best,
