Your idea for putting a message up where lots of people will see it .... I like that idea!.... partly because I too have pondered the idea of climbing up on overpasses and other places where high volume of people will see my message. I main snag I kept hitting was how to put into a few words enough of a message to get people's interest to look further. Your idea for the symbol takes care of that! Great idea. There are all kinds of possibilities here.
A quickie - 116 (that's 911 turned upside down, which is required in order to get to the bottom of the official story... but since it's turned upside down, this means you must go to the top to figure out what really happened, and at who's behest).
Or, you could come up with your own adpatation of international symbols... like those stick-figure symbols used for quickly informing strangers....walk.....don't walk....don't litter, put garbage here. The best one that I've seen is the stick figure wihout a head. The figure has a head, it just isn't on top of it's neck. Instead it is in his hands, in the process of being tossed into the garbage can, which is where the world's good little stick people put litter, but in this case, the stick person is putting their head into the garbage because they've been brainwashed into not knowing how to use their head anymore.
EDIT: this may not bee the most effective/positive symbol/message to enlist sleepy people to.....more honey and less vinegar.... you get the idea
Good idea. Go with it. Don't worry about the google video part. As long as you can get the info into some format that can be put onto the web, whether its a video or plain HTM file, all you need to do is start spreading it around to a few people, and then they spread it to a few people, on and on..... Good luck.
