"It took us a long time to figure out what a window really is," says Claes Granqvist. He’s a professor of solid-state physics at Uppsala University in Sweden. "It’s contact with the outside world. You have to have visual contact with the surrounding world to feel well. " So, windows and natural light are important for improving the way people feel when they’re stuck indoors.

But because it was incomplete and therefore could roll only very slowly, it admired the flowers along the way. It chatted with worms. It enjoyed the sunshine. It found lots of different pieces, but none of them fit. So it left them all by the side of the road and kept on searching. Then one day the circle found a piece that fit perfectly. It was so happy.
