- 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.

- 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.
