Wow, that's awesome! Super curious what project it is you run. (If you don't want to link it to your HN account, feel free to poke me directly, my contact info is in my HN account bio :) )
Sure; I have a Walltaker[0] (hi Gray) client with Buttplug support[1], it buzzes when your wallpaper updates! But my magnum opus was software akin to Edgeware[2] - basically, based on a Yaml config, it'll show you local or remote porn in various ways. That would have Buttplug support had Github not nuked the repo and ignored my reinstatement request for 4 months. I chucked it on Codeberg[3] if you're curious.
