Mike and Maaike Wallpaper
I collaborate a lot with architects and sometimes convincing an architect that you want to do something for purely aesthetic reasons is just not good enough. When I discovered the brilliantly talented Mike and Maaike had designed a series of wallpapers called Wayfinder for Rollout I saw it as "reason" enough, but l was happy to find out that this paper also serves a functional purpose within the context of architecture--even more reason to use it. "In 1974 a system of symbols was produced through a collaboraton between AIGA and the US Department of Transportation" and this is what Mike and Maaike drew inspiration from.
Here is Mike and Maaike's reasoning:
wallpaper = decorative
symbols = function
symbols + wallpaper = functional decoration
