If you're looking for a catalog of the cutting edge, I just found one.
Transmaterialis a 186-page compendium of some of the most flat-out amazing design technologies I've ever seen. Based on Blaine Brownell's "product of the week" mailing from the design firm nbbj, Transmaterial covers "materials, products and processes that are redefining our physical environment" -- a definition broad enough to encompass "biosteel" (biotech version of spider silk) to "3D textile knitting machines" (able to produce fully-formed textile products for medical use) to rubber sidewalks, collapse-preventing structure designs, urban knowledge maps and much, much more. Some of the items mentioned have already appeared here in WorldChanging (such as translucent concrete and LED lighting), and nearly all of them would make excellent WorldChanging entries (I must admit that I was sorely tempted to keep this catalog to myself as a "cheat sheet" for the next half-year's worth of posts...).
Each entry includes a brief (three paragraph or so) discussion, illustration, and link to manufacturer homepage where possible.
Best of all, Transmaterial is available as a free PDF download. The complete text is 11MB, but you can also grab specific chapters. WorldChangers will find all of the book fascinating, but should definitely take a look at the "REPURPOSED -- Materials which act as surrogates replacing precious raw materials conventionally used in various applications," "INTELLIGENT -- Materials that are designed to improve their environment and which take inspiration from biological systems" and "INTERFACIAL -- Materials which facilitate the interaction between physical and virtual worlds" chapters.
Transmaterial is a field guide to how today's design is building tomorrow.
