The darkening nights have become illuminated with beautiful lights.
I had an invitation to join a friend in London this weekend, to see the celebrations that mark the beginning of the Indian festival of Diwali. The week-long festival represents light triumphing over darkness, in the belief that good will always defeat evil. It seems many other cultures and places, including my home town, are also adopting similar ideas with annual displays, pageants or festivities.
I think most of us are pretty used to living with artificial light these days, but I've had fun taking a little moment here and there just to notice how everyday artificial lighting can create beautiful effects.
