Anyone interrested in building a (multi-lingual?) app for the magic mirror so you can connect your Smart / Connected Tootbrush from companies like Braun and Philips to it and use (age-related) games to help people and especially children to better brush their teeth (and perhaps in the future link that with your dental records).
Kolibree has already done something like that (https://www.kolibree.com/en/), but that requires a smartphone.
