queens - n queens screensaver SYNOPSIS
queens [-display host:display.screen] [-window] [-root] [-install] [-visual visual] [-delay microseconds] [-fps] DESCRIPTION
The queens program solves the n-queens problem (where, in this program, N is between 5 and 10 queens) using a straightforward backtracking algorithm. The problem is: how may one place N queens on an NxN chessboard such that no queen can attack a sister? OPTIONS
queens accepts the following options: -window Draw on a newly-created window. This is the default. -root Draw on the root window. -install Install a private colormap for the window. -visual visual Specify which visual to use. Legal values are the name of a visual class, or the id number (decimal or hex) of a specific visual. -fps Display a running tally of how many frames per second are being rendered. In conjunction with -delay 0, this can be a useful benchmark of your GL performance. ENVIRONMENT
DISPLAY to get the default host and display number. XENVIRONMENT to get the name of a resource file that overrides the global resources stored in the RESOURCE_MANAGER property. BUGS
It's not unknown for this and other OpenGL hacks to fail under hardware accelaration (UtahGLX) and take the X server with them. Texture images must be 16x16 or 32x32 or 64x64 etc. SEE ALSO

jigsaw - permute the screen image like a jigsaw puzzle SYNOPSIS
jigsaw [-display host:display.screen] [-background color] [-delay usecs] [-window] [-root] [-install] [-visual visual] DESCRIPTION
The jigsaw program takes an image, carves it up into a jigsaw puzzle, shuffles it, and then solves it. The image that it manipulates will be grabbed from the portion of the screen underlying the window, or from the system's video input, or from a random file on disk, as indicated by the grabDesktopImages, grabVideoFrames, and chooseRandomImages options in the ~/.xscreensaver file; see xscreensaver-demo(1) for more details. OPTIONS
jigsaw accepts the following options: -window Draw on a newly-created window. This is the default. -root Draw on the root window. -install Install a private colormap for the window. -visual visual Specify which visual to use. Legal values are the name of a visual class, or the id number (decimal or hex) of a specific visual. -delay microseconds How long to wait between shuffling pieces; default 700000, or 0.7 seconds. ENVIRONMENT
DISPLAY to get the default host and display number. XENVIRONMENT to get the name of a resource file that overrides the global resources stored in the RESOURCE_MANAGER property. SEE ALSO
