Immersed in Processing code at the moment, working on a new performance-piece to be premiered at the Three Choirs Festival this August. Tricky to explain just yet: it has to do with ecclesiastical geometry (see the Fish’s Bladder, above). There will be 12 singers – Musica Beata, in fact, the very choir I formed with David Mumford at Oxford 17 years ago. There will an element of performance-theatre, too. More soon.
