Good morning Prof. Anette,
Thank you for the presentation of the history of project management yesterday morning. As requested, here's the link for the Timeline 3D: http://www.beedocs.com/3dpresentations.html. It's for mac. A few clicks here and there and you'll be able to show this part in an even more engaging way, one that also clarifies the relationships among the different events.
For those who do not have mac, the web-based timeglider may be appealing: http://timeglider.com/.
