Advertisers are flocking to 3D projection mapping, a technique where the shape of a physical structure (usually a building) is used as a key part of the experience often creating amazing optical illusions. By projecting onto the building’s shape advertisers are able to create some draw-dropping visuals. I absolutely love this. We are all so used to thinking about advertising in terms of the web, text-ads and ROI but sometimes, the best advert is a good old fashioned big-budget spectacle….I look forward to seeing one first hand.
