I finished the installation today, so the relevant page of this blog has been updated. It’s some way from what I envisaged, but pretty effective, I think. Certainly it’s been a struggle getting it into place, so I’ll need a few days before I can judge it objectively, but I think it works, and I think it’s interesting. Whilst there’s more to do on it, I believe it should be a good resource for people taking part in the upcoming festival.
