I've noticed that epzilon feenyx has finally opened her website. She is a gifted character/cartoon-style artist and writer. German speakers also check out this short story of hers; in my opinion, it's the best she has published on the web so far.
Today I had a presentation for a computer science course ("Basics of Scientific Working"). The professor said it was very good. The topic I talked about, together with a fellow student of mine, was Ray-Tracing.
