An engineer’s perspective
I think that a better name for this device would be a pareidolia generator. As far as I could tell, the only essential components of the machine were the smoke machine and the audience’s cameras. If one was to take repeated pictures of any cloud, be it dry ice, water, or smoke from a fire, one would be able to identify all sorts of objects in the images.
In conclusion the stone tape projector is, as far as I can tell, a gimmick. It is based on scientifically flawed concepts, and is poorly implemented. Even the name does not seem to be original. The BBC made a drama in 1972 about a haunted house, where the haunting was the replaying of events which had happened in the past which were stored in the fabric of the building. This programme was entitled The Stone Tape.
