Science is not only a disciple of reason, but, also, one of romance and passion.
While going through some links to viewers for Mathematica graphics (including MathGL3d), I learned that Jens-Peer Kuska died in 2009. We never met personally, but in the early 2000s, I read many of his postings in Mathematica forums and we exchanged a few e-mails. His passion for Mathematica, mathematical visualization, and real-time computer graphics had a profound influence on LiveGraphics3D. His death is a great loss.
