"Smart Ideas for Smarter Cities" and it really is. There are so many posters just for advertising and nothing else. We found this campaign by IBM which is making advertising posters useful for the public. It’s a great idea, because everyone’s happy to have a bench coming out of the poster so that they can sit while they’re waiting for the bus. What if it’s raining and there is an advertising poster which is a refuge too, so that you can stand beneath for not getting wet? And for all those who have a wheelchair, a baby buggy or a wheeled suitcase there are these chutes which are awesome because the ease the passing of a stairway! There really should be more of advertisings like these!
