René Yedema April 25, 2015 - Log in to Reply I guess that when I would have learned to play the keyboard a bit harder I would have become a pianist. Wow, all those programming etc. makes my head turn crazy. This also explains why writing music and mathematics are so close, one of those things that made “Gödel, Escher, Bach: An Eternal Golden Braid” by Douglas R. Hofstadter so unreadable for me, despite my love for Escher and in a lesser way Bach (which is a nice link to your new video, Frank). Must have been a joy to work with David: he seems to be a very friendly guy.
