Three dimensional plotting of points. Produces a nice-looking 3D
 scatterplot with greying out of further points giving a visual depth cue

Quaternions and Octonions are four- and eight- dimensional
extensions of the complex numbers.  They are normed division
algebras over the real numbers and find applications in spatial
rotations (quaternions), and string theory and relativity
(octonions).  The quaternions are noncommutative and the octonions
nonassociative.  See the package vignette for more details.
