Wonderwall is an interior design firm from Japan.
I just found this website via Twitter, and haven't been able to stop looking at it.
They design offices, shops and more, everywhere in the world, and their work is real cool stuff. They couldn't have a less cool portfolio.
Just check out the awesome flash navigation used, and then click on their work, and be amazed. Bathing Ape Stores or Godiva Chocolateries are awesome.
