Tolkien called this idea “sub-creation,” suggesting that only God could create, in the complete sense of the word. But that humans, being made in God’s image, would by their nature strive to create. Anything we create uses what God gave us and would therefore be a lesser order of creation, thus sub-creation.

I recently visited Killarney and I thought it was a great system. As a tourist, the €2 was no big deal to have a cup for the whole week. Then I just returned it before I left and got the money back. They do this all over Germany and have branded cups for each town. It would be cool to see it more widely done elsewhere too.
