LOL, so much for Homeland Security, good thing they weren't bombs.

I think the things which have been in place for two to three weeks were the billboards and not the light-up devices. Also, judging from the way the ad company uses guerrilla, it could be the light-up circuit boards or devices or whatever the heck they are, are the guerrilla portion of the advertising scheme. While it does sound as if the ad company got approval for the billboards I don't think they addressed the thingies which were placed around stuff.

Sorry if I don't sound very articulate. I don't have any clue what to call the thingies which prompted the calls to 911.

Nope, the Flikr and Youtube stuff has been up for a while, showing the little glowy things in place.

Look for jackpot123 on those sites and you'll see pix, though he (or she) took down the vids of them being placed in Boston (for some reason LOL).
