I agree.
I often wonder why "spiral" is used to describe such staircases. Spirals are
actually 2D shapes (like a clock spring) wheras the 3D version is a Helix
(like DNA). Some pundits say that a helix is simply a 3D spiral with
constant radius.

Great image - the stairs, tiles and plant work together well, but the
guy on the stairs nad the B&W rendering really seal the deal.

I am inordinately fond of this photo, because normally when I do "street
photography" (i.e. people I don't know), they don't end up where I want
them.
I was positive I showed this on PDML before, but have found no indication
that I actually ever did. I have shown it on Facebook.
