In this presentation, conducted on 03-15-2010 @ University of Piraeus, I gave a small 30' presentation to my colleagues introducing them to Silverlight. The presentation was mostly based in interactive demos like augmented reality with the SLAR Toolkit, a Facebook Silverlight Client, Microsoft Health demos and a greek Project named "Virtual Fire" that forecasts fire probability and help prevent them. The slides presented are in Greek, but are free and available to anyone for download.
