in feb 2013 Youtube organised an event in Mumbai for advertising agencies about Youtube Impact in 2013
One of the GVC Design was used at the event.
This includes three things
1. Human Sensor
2. Video Control Circuit
3. Camera Flashes
As soon as some one enter the area, a video restarts, and four real camera flashes triggers after every half second.
Check the video here
Well, Video will not be able to convey the impact but the real event was just a Wow!!!!!! (as told to me by my customer)
