Website Response Times An Article by Jakob Nielsen www.nngroup.com Users really care about speed in interaction design...A snappy user experience beats a glamorous one, for the simple reason that people engage more with a site when they can move freely and focus on the content instead of on their endless wait. 0.1 seconds gives the feeling of instantaneous response. This level of responsiveness is essential to support the feeling of direct manipulation. 1 second keeps the user's flow of thought seamless. 10 seconds keeps the user's attention.

Chapel of St. Ignatius, Seattle, 1995–7 The exterior walls of the Chapel of St. Ignatius are made of large, complexly interlocking concrete slabs, a variegated golden-brown in color, and the roofs are clad in light grey metal.
