xmmstcl lets you control XMMS playback, skip, pause, change the playlist, change skins, and do everything else provided by the xmms_remote_* methods, which is almost everything from the standard user interface. It also has some things not available there, such as "XMMS onchange" which lets your Tcl/Tk application know when something happens in the player. The companion "TkPlayer" has samples for the most important functions and will keep XMMS busy by generating random playlists with songs that you haven't heard in a while.
xoris grabs the RGB color value of any pixel on the screen and dumps the color's name to stdout. The output can be printed either as hex (#b0958e), as a triple of decimal RGB values (229 229 229), or as an abstract name (gray90). xoris has only been tested on displays with a bit depth of 24 bpp.
