New Grasshopper foundation class video (in German)

Jan Philipp Drude (Gottfried Wilhelm Leibniz Universität Hannover - Fakultät für Architektur und Landschaft - Institut für Gestaltung und Darstellung) put together a Grasshopper tutorial in German that tries to lay a solid base for any computational designer. 

Most of the questions he got from students in the past were related to not fully understanding the data-structures, so he tried hard to get that across in the video.

Many thanks to Jan for sharing his know how!
