BTW, the VFD used on the first link happens to be Noritake, that is, the same brand associated with work for the NuTube project, and the inventors of the VFDs, so this might not me new for them at all. And also, by the way, almost the only brand still manufacturing VFDs that are easy to find on the market (at least buying one by one). And also, they make pretty tableware :D
