The Art of Shabbat

For this week's pre-Shabbat meditation: I've been thinking of ways Shabbat is like art. Here's what I've come up with so far:

• Art is not purely functional (i.e. a plain old door vs. a beautiful artistic door, a walk/don't walk sign on a street corner vs. the LOVE sculpture in the center of a courtyard).
• Art elevates common things.
• Art inspires and energizes (like a song that sticks in your head so that you can't stop singing it throughout the week).
• Creating art takes practice and lots of learning.
• Art points to an Artist.

Can you add any similarities between art and Shabbat to the list?
