@MockDeath Hey dude. They ARE 7 segment displays ;)
But yeah. BobW is right. Those are VFD. Vacuum Flourescent Display tube. And as such more in family with vacuum tubes than nixie (which are more in family with with neon lights and small neon bulps). One vacuum the other filled with neon. Funny though is that while many associates tubes with high voltages VFD tubes are often built for 9 or 12 v operation. Nixie or neon needs much more than that (typically >80 v).
This is a VFD tube clock with LED's shining underneath the tubes.

@scilonthreat Actually I think those are a Nixie Tube. They were around long before seven segment displays and they predate LED's.
