Programmable Vacuum Fluorescent Display (VFD)

Looks like an interesting toy!"
About the only reason I can see to use one of these (at least, once you get out of the geek subset that's into case modding) is for a home theater PC. Having an HTPC that could display current input, current song/video playing with time elapsed, etc. would be nice. And most LCDs have a visibility measured in inches (centimeters) rather than feet (meters).
Would probably want to be able to turn the brightness down though, since if it's too bright it's distracting in a darkened room.
And, all of that said, this display is too large to be used for most HTPCs -- the display itself is about the right size, but requiring 2 5.25" drive bays kills it.
