I wrote some stuff in the early nineties that still gets spun up once in awhile for testing purposes. Probably the only thing I've written in the past that still runs, or even exists on a disk. So that's cool. To tweak the question a bit, the things I've written recently that I'm most happy with are personal productivity/automation tools that I use all day, every day. I often need to do "a thing" between tasks. These "things" are not really part of the task, they're just needed to get to the next task, and they're disruptive enough in time and focus that I feel I've gotten off the train and then back on again. Now I really don't think about them, and my involvement with these things is only as long as it takes to type out the command.
