Our village has done this for years, organised by the Churches in an ecumenical effort. Each evening a window in the village was lit up and anyone who wanted to, especially children could go along and admire it, hear a reading, say a prayer and sing a hymn or an advent sing together.
After a few years the enthusiasm waned a little, or the organisers got overwhelmed, and it was reduced to every other day. Some nights (it was always at 6 pm) only a handful turned up but on other nights, crowds of up to 50 spilled out into the road.
Drinks and refreshments were not supposed to be served but some people did this anyway and people stayed behind for ages, chatting.
This year there will be windows lit up in the various church buildings and people are invited to walk over and admire them. Hopefully it will be back to gatherings outside people's houses again next year.
