Remember those amazing Windows Media Player graphics you used to like as a kid? You could stare at it for minutes, maybe even hours and not get bored. Well this particular experiment has something of that same touch and feel. 
Photo and Video Project

We only needed four things: a decent low light camera, a laser — preferably a pointer laser —, a high bass speaker and a device with internet connection and browser functionality. Next we creatively — believe me,  creatively — attached the laser to the bass of the speaker, pointed it towards a flat surface and fired up Google Translate on our device.
Next, we used Google Translate's dictation function to let it read "Gravity" out loud.The camera was focused towards the wall. We filmed the whole thing instead of taking it shot by shot.
As you can see below, the result was somewhat mesmerising...
A constant frequency and amplitude before dictation.
This first part most likely indicates the dictation of "gr". There isn't a lot of variation going on here regarding amplitude or frequency.
This next part seems a little more aggressive. The harshness of the letter "a" and the abrupt tone change on the letter "v" would probably have caused this kind of variation. 
Again, a rather aggressive looking form. Probably because of the vowel "i" in combination with the abrupt tone change of the following consonant "t".
Still a tone change going on here... 
The longer tone of the letter "y" is shown here. Not aggressive but rather calm.
After dictation, we come back to a constant frequency and amplitude as seen before the dictation.

If you would make a promotional video for an exhibition for example. You could slow down the fps of the video, multiply the images and create something as shown below. A pretty neat effect.​​​​​​​
