Creative thread. My other carreer has me very involved in the horse industry. To make a point, I include magic in numerous presentations (American Horse Publishers Association, etc.) as well as having done shows a the national Pony Club meetings. I recall using a chick pan to explain equine nutrition and make a new horse feed. I'm aware of a vanishing horse and appearing horse illusions but have never seen them performed. I would imagine the biggest issue is finding a cooperative horse. An Olympic rider has been asking me to come up with some ideas they can use on horseback in large expositions.
