.SH DESCRIPTION
Loads several random images, and displays them as if lying in a random pile.
The pile is periodically reshuffled, with new images coming in and old ones
being thrown out.

This program requires a good video card capable of supporting large
textures.

To specify the directory that images are loaded from, run
.BR xscreensaver\-settings (1)
and click on the "Advanced" tab.
