# tvid

This is an app that lets you set all the kiosk/display TVs in your
organization to the same URL. Each will be cookied with a unique ID that
will display on each display in big letters, with no preconfiguration
required.

Log in to the admin panel and enter the URL for that TV ID, and within 60
seconds, that display will bounce to that URL, or any other time it turns
on.

# todo

* make display id animate: https://codepen.io/stezu/pen/cmLrI
