Jordivayreda Projectteam - A Spanish design studio has come out with this very one of a kind stairs to link you from your second floor to your first. Pushing designs to the limits but it sure looks dangerous if you put someone heavy on it. Again it is something which you thought it would only feature in video games haha. More info here. Looks good but not practical. Jordi actually dropped me an email to explain the reasons and secrets behind constructing such a staircase so check out the pics she sent me.
