Simply put, it's incredibly cool. It's used around the world as a new communication tool. Basically, it's about projecting images on objects, typically buildings, but in alignment with their features. It brings life to inanimate objects. It's fantastic for live events, and it has a great afterlife in the world of viral videos...

The cost of content is based on duration and complexity. And the cost of projection is based on the size of the wall, the number of walls, and the number of days.
