Actually, my hope is that people use this technique more often until it stops looking magical, which is why I submitted the link in the first place. I wanted to give it more exposure. I've used this technique a couple a few times to deliver presentations, and it seems that all that people notice is the hacker typing, or at least that's what they most comment on, instead of the content of the talk. I don't know if they really are being distracted away from the content, but in case they are, I want the technique to be pedestrian.
