+musicians, visual artists, performers, researchers, and developers to create
+software graphically, without writing lines of code.  Pd is used to process
+and generate sound, video, 2D/3D graphics, and interface sensors, input
+devices, and MIDI.  Pd can easily work over local and remote networks to
+integrate wearable technology, motor systems, lighting rigs, and other
+equipment.  Pd is suitable for learning basic multimedia processing and visual
+programming methods as well as for realizing complex systems for large-scale
+projects.")
