Along the lines of my other spec promo ("Do the Math"), I liked the idea of Accenture's accent symbol doubling as a math symbol--or even more than one, say, an equals sign morphing into something even greater.
We had a lot of great personalities in the department, and last year, we made the most of them by filming them and having them draw their own art scribbles over themselves. Well, I took some of that, made it black and yellow to fit the AI brand, and voila! A dynamic statement with the heart and smarts of the department itself!
