Marc Rettig, co-founder of FIT Associates in Pittsburgh, joins IxDA at Razorfish NYC to talk about the journey he and his firm have been taking, to shift from familiar project-and-product-oriented design work, to work intended to affect positive change in the world. Along the way, he talks about sustainability, the intimate effects of design, the power of immersion experiences on product teams, the organically complex nature of modern design challenges, and more.
