The launch of the new Nokia phone in a fight back against all the iphone/droids etc hit London with this very impressive and massive 3d projection on Millbank Towers in london. Which presumably has the right aspect ratio as a building to show the smartphone in a good light.

This on building projection is getting really popular and is really a giant augmented reality application that requires no headsets. Projecting onto the real world in any form makes it a good shared experience and the project technology is precise enough now to allow for the surfaces of building to be taken into account.
According to the youtube information “Each of the 120 metre high building’s 800 windows were covered with vinyl as 16 powerful projectors, stationed 300 metres away on the other side of the river, beamed 3D images onto the structure”
I hope the phone is as good as the advert!
