Every day I see wild concept videos of futuristic homes. Last week, I saw a floating pod that you could live in. The bedroom was underwater and your living room was up top. A couple of years ago, someone on the SketchUp team watched this video which led is to us making a digitally fabricated Wikihouse.
I love insane, ridiculous, and forward looking concepts of the future. Not being bound by budgets, design norms, and consumer demand can allow for anyone's creativity to produce some amazing ideas.
