In an alternate universe, Alienware has a popular chain of Alienware stores, with award-winning staircases. It all started with the Egg MP3 player...
Mixed feelings about this one. I'm sure enough steel would make it stable but all those vertebrae joints would freak me out if I had to step on it and think about it at the same time.
Yeah, but really: By far the heaviest part of the stairway is the stairway itself. You (and your friends, and whatever the lot of you might be carrying) are just a drop in the bucket, like a motorcycle on a 6-lane interstate highway bridge; it doesn't even know you're there.
Looking at the pictures, I get the impression that there's a continuous tubes the entire length of the stairs and the vertebrae are short cylinders around this. Which would be helluva lot stronger then a bunch of cylinders connected to each other.
Missed the "and people think I'm hard to buy for" remark.
