Maybe we should have a contest: the best TV or oscilloscope or panadaptor or any other design of a useful product using these small tubes.

Most camcorder EVFs are completely self contained video monitors - all you have to do is feed them either 5vdc or 12vdc and a composite video signal and you are all set. I built several of these, and have a lot more in my collection to complete someday. I used to buy junked video cameras and camcorders from local electronics junk stores, but now those stores are all gone, so I get my EVF modules from eBay. My favorite EVF comes off old Magnavox VR8276BK01 Color Newvicon Video Cameras because they are completely self contained and detachable with a built-in factory cable and connector. The only thing that they do not have is audio capability.
