Show HN: Metascreen, free digital signage that doesn't suck

I've been working on this project for a while. Free tier (single display) will be free forever so please use it and provide any feedback you have.

USE CASES

Use it to show real-time traffic or social media feeds in your office lobby.

Great for bars and restaurants to show their specials and menus.
