I've been going through Klein Dytham's website, and I'm astounded by absolutely every one of their projects. There are very few artists who's complete works I love; for instance to me the entire Red Hot Chili Peppers catalog, or anything by Peter Zumthor.... Klein Dytham just joined those ranks. I'll feature a few projects but spend some time on their website looking at all their stuff. All of these have their locations with maps on the website.
They are a Japan-based firm but the principals are 'international'. See their bio. They were also the founders of Pecha Kucha, which is a informal forum for artist to show their work. They have accomplished the feat of setting up a legacy, something that will outlast them. That's what all great people strive for right?
