Show HN: Generate custom MTA Subway displays

Last week while sitting on the subway I noticed the displays in the newer (R211 maybe but I don't really know my trains models) display what are essentially captions of the overhead announcements. As it was flashing "ALCOHOL" on the screen I started pondering what else one could display on these screens, just for fun. I ended up creating a generator and now I hope you'll enjoy it, and maybe leave a message in the gallery a la guestbooks of the early internet.
