What If...?: The Architecture and Design of David Rockwell

I have always been fascinated by stairs. Especially as kids we had these jumping games, where you could hold the side railing, but had to jump on the stairs down by skipping based on the number called out by the other player.

Sitting on the stairs too, gives a very different perspective of the leading and trailing steps. Even when you dont get a vantage point or a view, the mind registers the levels and probably thinks in gradations.
