Ok now..these are a set of stairs close to my home..Since I as very young studiet the art of
M.C. Escher...and later on climbed numerous stairs of historical buildings..I am intrigued
by them,,This concept of climbing and often being presented to different angles on the same view.
It is almost philosophical...correction it is philosophical;-)
By the way ...go study Escher: http://www.mcescher.com/
