Flac File Players

RandFlacPlay.py is a Python language script that recursively finds all the flac files in a directory tree and randomly plays them. Playflacs.py is another Python script that plays all the flac files in a specified directory, then exits. Both can easily be modified to play .wav or .mp3 files.

Unix X11 Color Table Editor

This program is very useful for manipulating color tables under various Unix operating systems. It only works under an 8 bit color model, which goes back to the Sun/Solaris system that it was developed under. The program compiles under Linux, to use xacte, start the Linux X server with the -bpp 8 option to use the 8 bit pseudocolor mode.
