|-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.|
|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.|
|The X font to use. Phosphor can take any font and scale it up to pixelate it. The default is fixed.|
|-scale int||How much to scale the font up: in other words, the size in real pixels of the simulated pixels. Default 6.|
|-ticks int||The number of colors to use when fading to black. Default 20.|
|The speed of the terminal: how long to wait between drawing each character. Default 50000, or about 1/20th second.|
|-pty||Launch the sub-program under a PTY, so that it can address the screen directly. This is the default.|
|-pipe||Launch the sub-program at the end of a pipe: do not let it address the screen directly.|
The command to run to generate the text to display. This option may
be any string acceptable to /bin/sh. The program will be run at the
end of a pty or pipe, and any characters that it prints to stdout
will be printed on phosphors window. The characters will be printed
artificially slowly, as per the -delay option above. If the
program exits, it will be launched again after 5 seconds.

If you have the festival(1) text-to-speech system installed, you can have it read the screen as phosphor prints it:
phosphor -program \ xscreensaver-text | tee /dev/stderr | festival --tts
phosphor -delay 0 -program tcsh
|-esc||When the user types a key with the Alt or Meta keys held down, send an ESC character first. This is the default.|
|-meta||When Meta or Alt are held down, set the high bit on the character instead.|
|-del||Swap Backspace and Delete. This is the default.|
|-bs||Do not swap Backspace and Delete.|
|-fps||Display the current frame rate and CPU load.|
By default, phosphor allocates a pseudo-tty for the sub-process to run under. This has the desirable side effect that the program will be able to use ioctl(2) to fetch information about terminal parameters and window size, which many programs (such as top(1)) need to run properly. phosphor will also set the environment variable TERM to vt100 in the child process.
Any characters typed on the phosphor window will be passed along to the sub-process. (Note that this only works when running in "window" mode, not when running in -root mode under xscreensaver.)
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. TERM to inform the sub-process of the type of terminal emulation.
