If this is true, then "tools for thought" can never be "calm technology," since creative thinking is not just about problem solving, but problem finding.
I completely agree that—when you're talking about thinking tools—"technology should amplify the best of technology and the best of humanity." But I don't see how it applies to any of the examples given (including "lavatory sign," trend graph, office window, and, of course, teapot).

OT, but it seems no technology is so calm these days that people can effectively proofread the first 58 words of their web site—not even an author promoting her book.
