Computer
screens have the disadvantage that data can only be displayed as two-dimensional
plots, while human visual perception is capable of perceiving 3D scenes.
Thus it would be a good idea to add a third dimension to the screen display.
While this is impossible due to the physical setup of the screen device,
there are some tricks to create a pseudo 3D impression. One trick is to
rotate the 3D data and continuously update the 2D screen projection. This
gives the illusion of a third dimension. The data laboratory has a command
to select any three variables and to rotate the selected three dimensional
subspace on-screen.
You may take a look at the following 
which
shows a banana-shaped data set. You can rotate the data by moving the mouse
while holding down the left mouse button.
