An excellent graphic from the National Post on the number of adherents of the world’s believing and non-believing constituencies. What factoid surprises you?
Isolate the musical notes of the first violin playing the fourth movement of Ferdinand Ries' second symphony. Then create a visualization that gives the most untrained ear an idea of the sweeping undulations and dynamic energy of the German composer's piece. What you get is this smart, real-time look at the Zurich Chamber Orchestra (Zürcher Kammer Orchester) in the shape of a roller coaster:
"The camera starts by showing a close-up of the score, then focuses on the notes of the first violin turning the staves into the winding rail tracks of the rollercoaster. The notes and bars were exactly synchronised with the progression in the animation so that the typical movements of a rollercoaster ride match the dramatic composition of the music."
