The coolest use of a gas plasma display I saw in person was at my teenage software engineering internship. We had the coolest engineering workstation computers, Sun and almost everything else, with the huge CRTs... but strangely cooler, in a way, was the sysadmin's Ethernet diagnostics device. IIRC, it was built atop a rebadged Toshiba laptop with orange gas plasma display, and included a glowing bar visual display for network traffic (packets? collisions?), with corresponding geiger counter sound effects. A modern IPS LCD or OLED just wouldn't pair as nicely with the sound. (Analog gauges or Nixie tubes would work, though.)
