NYT article by Allison Arieff that features wonderful and, indeed, ludicrous concept illustrations by inventor, author, cartoonist, and former urban planner Steven M. Johnson. From the article:
In discussing his often fantastical, sometimes silly, sometimes visionary concepts, he has said, “If I could use two words to describe what it is that I enjoy it is that I love to be sneakily outrageous . . . [It may be that] I have decided an idea has no practical worth and would never be likely to be adopted seriously (like most of my ideas), but I like it anyway.”
After seeing sleep-in cubicles for seniors you’ll know what he means by sneakily outrageous.
