This is just a WarpOS recompile of the original program by Troels Walsted Hansen.

Original Readme:

Introduction
¯¯¯¯¯¯¯¯¯¯¯¯
A little hack based on xripple by by Carsten «Rasterman» Haitzler 
<s2154962@cse.unw.edu.au>.

Creates a water ripple effect at the bottom of your default public screen
(usually the Workbench screen).  Pure eye candy.  Includes source.  Should
work on all OS 2.0+ Amigas, the faster CPU the better.  020, 020881, 040881,
and 060881 versions included, compiled with both SAS/C and GCC (GCC version
seems slightly faster here).

Enjoy!

Usage
¯¯¯¯¯
Just run it from a shell.  You can quit it by pressing CTRL-C in the shell.

There's a few arguments:

HEIGHT/N  - height of the water, must be between 1 and 32767, default is 64
WAITTOF/S - use the WaitTOF() function to time frames (should be used on AGA I
            think), default is to use WaitBOVP() which is best on CyberGraphX.
NOWAIT/S  - don't time frames at all, just pump them out as fast as possible.
QUIET/S   - don't print banner and fps info.
USAGE/S   - print usage and quit.

Version history
¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯
Ripple 1.1 (12.11.97)
 · If HEIGHT was < 6, Ripple would read from completely bogus addresses.
