Yes. Manual page: phospor
Use xscreensaver as screensaver. See Configure screensaver in Ubuntu and set it up to use phospor in the advanced tab:
phosphor -root -delay 50000 -scale 6 -program htop
- root : Draw on the root window.
- scale (int) : How much to scale the font up: in other words, the size in real pixels of the simulated pixels. Default 6.
- delay (usecs) : The speed of the terminal: how long to wait between drawing each character. Default 50000, or about 1/20th second.
- program (sh-command) : 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 phosphor's 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.
untested until later today; the phosphor command might need an absolute path.
