Stairway to Heaven
This is why I love boingboing. Where else can I find the prototype for my next staircase? (Of course, if I had a two-story house.) Nevertheless, this staircase is too cool. And don't worry. The handrails are made of the same transparent material as the risers -- they're there, but not there. Lovin' it.
PS: What does this have to do with marketing? Not much, except marketing is cool and so are these stairs!
