Art & Bricolages Emoji

This page contains a couple of emojis illustrating hobbies and art. A palette with paint and a painting itself (or a drawing, it depends on the degree of your nerdiness). A needle with a thread for sewing. And two masks that symbolize theatre.

A question for those who enjoy not only copying emojis, but also ask and answer philosophical questions. What is art? When does a regular hobby become art?
