The same content on all websites at once, just for a minute, can it be done? Could it not be … beautifull?

I wonder if it’s possible to show one message on all screens at once on all media.

Like a window poster you can print from an email and show it to everyone passing by.

An internet billboard message that’s visible everywhere in the world, at the same time.

And then take pictures, make soundrecordings and videos of peoples reactions and responses.

A 1 world, 1 message collaboration crowd thing that makes the world stop for a second and think.

I’ve never heard of it before, has it been tried or even thought of?

Now that it is inside my head i don’t think i can sleep, this idea will probably haunt me for some time to come. What do you think?
