RE: we are all made of frequencies--

yes, and most human skulls, because of the proportions, resonate at middle C -- or as some of us like to know it, 660Hz.. so if your local service is in 60HZ AC(all of US, parts of Europe, and souther part of main Japanese island (tokyo and north are 50Hz) (i don't know rest of the world)
But if you are in the 60Hz range, you can do this..

sit about 6 to 10 feet (2 to 3 meters) away from a TV screen, and hum middle C .

since 60 and 660 are related frequencies, what ends up happening is your head starts to vibrate..in a resonent frequency and since you TV is being refreshed at the same rate, the picture changes.. depending on your own heads personal frequency, how good you are at mantaining perfect middle C, and the distance, you tv pictue my "break up" or you might be begin to see the raster fresh (that is, you'll see the image being updated (actually you see ever 6th image being updated) or the image might seem to jerk, almost as if it is being reversed.. (a little alcohol, to relax you helps!) its a fun weird thing to do at a party..
