Work Samples

“Einstein was once asked by a reporter if they could see his lab. He took out a pen and pointed to his temple.” — Author unknown

Much of the work we do is testing – which is hard to show samples of in a portfolio. And we are precluded from showing the results of testing as part of the non-disclosure with our clients. Our design work has other limitations for a traditional portfolio: we are part of the team on most designs – we work on specific elements and do not have complete creative control. To claim the designs we work are solely our work (and hasn’t changed since we last worked on it) is unfair to us and to our clients.

In lieu of direct work samples, we have assembled publications, presentations, and other work that should shed light on our perspective, approach, and the work we do. Hopefully this material will help (though talking to us directly will shed even more light).
