<_description> XMountains generates realistic-looking fractal terrains of snow-capped mountains near water, with either a top view or a side view. Written by Stephen Booth. This is not included with the XScreenSaver package, but if you don't have it already, you can find it at <http://www.epcc.ed.ac.uk/~spb/xmountains/>. Be sure to compile it with -DVROOT or it won't work right when launched by the xscreensaver daemon.
