Chronovisor

The Chronovisor (from Italian cronovisore) is a device that allegedly enables users to see and hear scenes from the past via an unknown process involving harmonic resonance. It is said to have been developed in Italy by a group that included Benedictine musicologist and exorcist Pellegrino M. Ernetti, who first made public the invention in an interview with Vincenzo Maccaloni in 1972 for the Italian weekly newspaper La Domenica del Corriere. For his part, Ernetti stated the "machine can record the energy of thought from space," warning that the "discovery could be a tragedy for humankind," threatening to "curb freedom of thought, speech and action" as it could "tell what neighbor or enemy is thinking."[M]
