I was very certain I had like 50 unused horses laying around somewhere, I intended to build something including some of these. But after some hours of searching, I could not find them anywhere.
But it seems a fellow LAFer is kind enough to send me some of his spare horses, so in the end the project may well go through!
Some inspirational pictures:
I want it to be grimdark/ creepy, as you may have guessed from the pictures.
