Um, they've been doing this for quite some time, longer than you in fact.
For example, the Whitney Museum of American Art (Dec. 2001-Feb. 2002). http://www.languageremoval.com/longcount.html

I was aware of the Whitney exhibit, it is completely unrelated to my project. In the Long Count, the video was manually retouched frame by frame to remove the fighters. I edited the words out of videos of political speeches long before he ever did. And if that's not good enough for you, my video editing work was exhibited (uncredited) at the Whitney Biennial 2 years before theirs.
