Has anyone thought about building a Nixie tube interactive topper? Prices on IN-14 tubes have gotten very reasonable and there's a bunch of open source software for Audrino available. Lots of off the shelf tube shields with sockets too. I think I'm going to get a clock kit and 3D print some kind of enclosure. You could potentially show high score, ball in play, etc but I don't have the software skills for that. I'm generally not a fan of most toppers, but in this case if it's interactive and matches the existing steampunk graphics, it would look awesome.
