This is exactly how a project is meant to be done. The client (remaining anonymous for the time being) is smart and believes in the idea, and has the confidence in the people they have involved in making it to let them do their thing. For our part, we know that we're working with talented people who know exactly what to do to make it as good as it can be, so we gave them the space to do it. All in all, a collection of people who want to go about things in the right way, in order to get the best results.
A big thanks goes to [the client] and to Mark, Sean, Sara and the gang at Coy! for making the impossible possible (and for being pretty fucking good at what they do).
This is what happens when companies with exclamation marks get together.
