Speaking of Cool Tools, Kevin Kelley's recommendation of Smart Home Hacks made the cut for inclusion in the massive and awesome printed Cool Tools compilation. (As did my write-up of Delivery Status.)
The Cools Tools book is very reminiscent of the Whole Earth Catalog and promises hours of browsing and discovery. Frankly, I'm in awe at both the book and body of work from which it grew. If you're interested in publishing, the backstory about how the book was created is well worth reading too.
