   Section A

This is a 3D model of a Sun machine.  The model was taken from the very machine on which I now type.
Lighting has been added and can be toggled with the 2 and 3 keys.  A singular
light has also been added that remains on.  In addition, the user can
increase/decrease the amount of ambient lighting using the + and - keys.  The
old functionality is still in tact in that the object can be spun with the
arrow keys, and the view mode can be toggled between solid and wireframe
using the w & s keys. */
