I have noticed that if you trill your tongue while you are looking at a digital clock the numbers seem to wave and even move up and down separately, this works best if you are relatively far away and if the display is large. Something to a similar effect happens with a regular computer monitor or T.V. I noticed when I tried this with my laptop that it did not work very well, even at different distances. Also, if you trill your tongue at different speeds the effects on the object change, for instance at lower speeds the computer monitor seems to vibrate but at higher speeds the screen seems to wave (the reason that I used the computer monitor as an example is because my computer monitor works the best for this). I believe that this has to do with the trill vibrating your head so the image appears to move, but I would like to know why with the digital clock the numbers seem to move independently, or separately up and down.
