rocks - animation of flying through an asteroid field

DDDDEEEESSSSCCCCRRRRIIIIPPPPTTTTIIIIOOOONNNN
The _r_o_c_k_s program draws an animation of an asteroid field
moving past the observer (or vice versa). Sometimes the
observer picks up spin on Z axis.
OOOOPPPPTTTTIIIIOOOONNNNSSSS
_r_o_c_k_s accepts the following options:
----wwwwiiiinnnnddddoooowwww Draw on a newly-created window. This is the
default.
----rrrrooooooootttt Draw on the root window.
----iiiinnnnssssttttaaaallllllll
Install a private colormap for the window.
----vvvviiiissssuuuuaaaallll _v_i_s_u_a_l
Specify which visual to use. Legal values are the
name of a visual class, or the id number (decimal or
hex) of a specific visual.
----ccccoooouuuunnnntttt _i_n_t_e_g_e_r
Maximum number of rocks to draw on the screen at
once. Default 100.
----ssssppppeeeeeeeedddd _i_n_t_e_g_e_r
A measure of the speed with which the observer and
the rocks pass each other, from 1 to 100. Default
100, meaning ``very fast.'' If you're on a slow
display connection (the animation looks jerky) then
try making this number smaller, and/or decreasing
the number of rocks.
----ddddeeeellllaaaayyyy _m_i_c_r_o_s_e_c_o_n_d_s
Number of microseconds to delay between each frame.
Default 50000, meaning about 1/20th second. Compare
and contrast with -_s_p_e_e_d, above.
----nnnnoooorrrroooottttaaaatttteeee
Don't rotate the observer; just fly straight through
the field.

to get the name of a resource file that overrides
the global resources stored in the RESOURCE_MANAGER
property.

There should be an option to display doppler shift (a
gravity rainbow.)
Speed of rotation should be settable.
Default speed of rotation should be relative to forward
velocity.
