 In its original form, a Dreamachine is made from a cylinder with regularly spaced shapes cut out of its sides.That cylinder is then placed upon a record turntable and rotated, depending on the scale, at either 78 or 45 revolutions per minute.A light bulb is suspended in the center of the cylinder with the rotation speed making light emanate from the holes at a consistently pulsating frequency range of 8 – 13 flickers per second.
