Instrumental Transcommunication or ITC is a technique that involve the use of electronic means to contact spirits, the term was coined by Professeur Ernst Senkowski. The machines used are typically televisions, fax machines, tape recorder, video and digital cameras. One of the pioneer of this kind of mediumship was William O'Neil, he was able see and communicate with two scientists working from the 'dead zone'. Using a modified side-band radio the voices of 'dead' scientists were captured on tape in intelligent and responsive conversations. Skeptics think that ITC recording are hoaxes. Skeptics believe that ITC is simply the free interpretation of natural phenomena.
