I discovered what3words.com whilst watching a random YouTube clip the other day. It was on this channel if you're interested.

What they do is really fascinating to me being someone who's interested in maps and tech. Essentially they've mapped the entire world into 3 by 3 metre squares and then assigned a string of 3 words to each of those squares. Test the map out here map.what3words.com

For example, if I input fall.through.indoor I get this really specific location at the Melbourne Cricket Ground. That is excellent for finding where a mate is a stadium. In the pod I'm also thinking about how awesome this might be for events, delivery companies, uber and people organising picnics.
