While looking at an oscilloscope, a human-like figure appeared on the

At work about 50 years ago we had a oscilloscope that could project
onto a screen for talks and demonstrations. It was just a plain old
scope mounted upright that aimed the image onto a oily reflector. It
had to be in a dark room to make the projection clear. One day an
insect fell into the oil. Now that was a scary image.
