So my neck has been hurting a lot lately and I've been using this vibrating massage pillow to loosen it up. I took the vibrator out of the pillow(much stronger vibrations this way) and I was walking around my house earlier holding this thing to my neck and I noticed that if I look at a digital clock the numbers apear to be moving around. The amount they move varies from clock to clock, the bigger numbers seem to move more. It's quite a strange sight. The body of the clock and everything around it apear normal while the numbers jump around. Does anyone have a clue as to why this happens?
In order to get this to work you have to press something that vibrates firmly onto your neck or head. If you just hold it lightly it won't work, and other parts of the body don't work. Also, I've only tried this with LCD clocks with red numbers.
