These are really my brothers that are the original pranker and prankee.
First of all, I am so proud of my brother. He started this thread, and got my other brother. Much mucho props go out to avi, for making everything possible and keeping this from being a one page thread about sticky keyboard jokes. I'm conflicted on the digg, cause I don't know if he needs that much notoriety (although I digged it myself)
Since avi seems to be open to suggestions, I have a few. I don't know if these are possible, but they might add something.
Video. If possible, display to the prankee a live feed on a 1-2 second delay. This, imho, would add to the shocked, confused looks that everyone is looking for. If you could have two video windows open, and one on a 2-3 second loop of "the act" originally being caught, this would be phenomenal, and add a touch of frantic behavior to the mix.
Also, I believe this has been suggested already, but changing the text speak to an MP3, rename any MP3 to XX.MP3 and have it play at some point.
Once again, major props to avihappy.
Derek, thank you for the ammunition.
