As you are all burning away the midnight oil, you may find these interesting.
The Aeolus clue made me think of "The Singing Ringing tree" which is on Pendle Hill in Burnley, not far from where I live, this in turn put me onto another link with a couple more Aeolus' down south (Eden Project & Canary Wharf) by the artist Luke Jerram. There are a few short clips to watch on these links, hope you enjoy them
