Here is another animation which moves along the edge of the spiral. The yellow green, green, and blue polygons are all strings and are embedded with the "Strings" landscape image. Yellow green is violin, green represents violas, and blue is for double-bass. The pink polygons are piano notes. Click to see the 2D drawing of the "piano" landscape representing all percussion instruments which have graduated keyboards.
Mouse over and you will see an animation of the musical structure from within the parabolic spiral. If you click on the images you will see large stillshots.
