My grandparents practically don’t leave their home anymore. So the next time I visit them, I would like to show them something they have not experienced or seen before.

I thought of taking them on a trip to different places using Google Earth (or something similar). I just want to go a little more interactive than just showing them videos or pictures.

I am limited to my laptop (and their TV + maybe a Chromecast).

Do you have any interesting internet things or places you would show your grandparents?
