the wonderfully creative martin poole is organising a day in december in brighton on the art of ritual. the blurb says 

The boundaries between art and ritual are becoming more and more porous as artists engage in performance work with highly stylized routines or actions and celebrants (religious and non-religious) explore the use of art to help people mark the important milestones in their lives.  This day will bring together practitioners in all forms of ritual and art to share ideas, talk about trends, experience artistic rituals and enjoy performances.
The event will include performance art, discussion, networking opportunities and a Gravetalk Café.  The afternoon will conclude with a visit to the Beach Hut Advent Calendar opening for that night and will be followed by an evening performance of ‘Mass’ by Amy Mason.
