Things that go bump in the night - Near Downton, Wilts, England, the group are pictured at work around the Psychopen, an instrument based on the Planchette, but instead of having only one pen, this has four. The platform is square affording a much larger area for the fingertips of participants. This construction also makes it much mroe rigid and because it touches the table with only the tips of four freely moving ballpoint pens there is very little friction. The instrument therefore moves extremely easily and can write with considerable speed. It is also possible to tell from which direction the motivating force is coming as the pen at that corner writes most legibly.- ?TopFoto
