At the moment the idea is to run one 24 hour prayer session every month. The idea comes from the book, Red Moon Rising, and the 24 hour continuous prayer around the world that they have set up. Take a look at their site http://www.24-7prayer.com/
The prayer tent is about 2m X 3m with areas for prayer on different things. There is an area with a cross, a “wailing wall”, a “world wall”, a “worship wall”, books art materials etc. I find it a really easy place to pray.
