Adding an LCD Status Screen to a PC

"The real estate on your screen is precious, and with your PC's vital stats, Winamp info, game stats, stock tickers, news tickers, sports scores, and more, it's easy to run out of space. How about adding a liquid crystal display (LCD) that can show this type of information?" Seems pretty straight-forward ... " Yes, but can you make one as as pretty as this one?

Hardware ?

How about creating a Computer MODS section ?

It isn't the first time that this is suggested, and with the increase of case mods posts recently (and others sort of mods), this would make sense.

Those LED scroller things...

I've always wanted to hook up one of those big LED text scroller things that you sometimes see in shop windows to my PC, to display the time and things like "You have mail!"

But I don't even if know if it's possible...

More usefulness...

Several months ago there was an article on /. about the BriQ, a powerful Linux/PowerPC box squeezed into the size of a CDROM drive. The only connectivity of the unit is an ethernet jack, a serial port, and the front panel. A couple weeks ago I was given a project at work to develop a menu system/UI that would run on the front panel of a BriQ to be used as a demonstration unit. The BriQ's front panel consists of a 20x2 VFD display, a tri-color (red, green, yellow) LED, and 2 buttons.

Control of the panel is simple: writing to /dev/lcd displays characters on the VFD (or changes the LED color w/ control characters), and reading from /dev/lcd gets the state of the buttons. I was able to develop a UI (in Perl) that used those buttons and the display to not only display status messages, but perform basic system tasks like rebooting and setting manual network configuration settings.

Unfortunately none of the displays that I've seen online have included anything in the way of input on the same serial connection, which would increase the usefulness of these status displays immensely. C'mon, don't tell me X (especially w/ proprietary drivers like nVidia or Matrox) has never frozen on you, leaving you to find some other machine to ssh in from and fix things. With a simple secondary I/O system like the one on the BriQ, one could not only have a really cool gadget, but also provide a needed backup interface for those computers that do double-duty as workstations and servers. Or even to get monitorless servers started up on strange networks w/out DHCP.
