Yahoo! Picks - bringing you the best of the Web since 1995

We should have written this Pick months ago. But we're incapable of coming near Etsy without abandoning all sense of time, obligation, and, let's face it, fiscal responsibility. Forget any other web phenom you've heard about recently, the Greatest Current Thing is Etsy. Here, creators and lovers of fine (and funky) handcrafted items buy and sell a wide variety of goods. Tote bags, artists' books, photographs, knitted wear, collage work, jewelry, ceramics, polymer beasties, they're all here, plus much, much more. Surely, we've already lost readers to the addictive, ebullient site, but for those of you still with us: Begin with the main showcase, check in with the featured seller, experience the space-craft continuum with the "time machine," and perhaps take a joyful romp through the "shop by color" section. And then, let your fancy guide you. You've entered the joyous realm of Etsy.

Someplace off Grenada, a ring of steel and concrete women stand rooted in the ocean floor. Eyes closed, holding hands, facing outwards from the circle, these immobile figures have stood guard for about a year. If their sculptor has his way, they will stay there for as long as they endure the effects of sea water, algae, and other aquatic agents. Jason Taylor planted the submerged women—and other figures in their concrete family—as a project in coordination with the island's ministry of culture. This "artificial reef of sculptures" represents the people of Grenada and "highlights the environmental processes" forever at work in its waters. The generous supplementary site not only shows off the sculptures in their marine home, but walks viewers through the process of creating the pieces, shares two slideshows of what happens to the work over time, and finishes with a video that indicates how eerie—and amazing—it must be to dive among the deep sea bodies.

Who doesn't love puppies? Even 3-D plastic ones can earn our oohs and aahs—at least, this pack does. The Puppylove Project asked 36 designers and artists to create something unique from a plasticene model of a bulbous-nosed, short-legged canine. The resulting brood will be auctioned beginning December 6, with 100% of the proceeds going to the University of Miami Sylvester Comprehensive Cancer Center. A tour of the kennel reveals puppies who are furry, fancy, and floral. One doggie called Charlie boasts over 500 Swarovski crystals and 1,000 sticks. Another, dubbed PFLIP, is festooned with computer hardware and electronic components. The appropriately named Goldy flaunts an entire coat of 24K gold leaf. You wouldn't want to leave these pups at the dog park. Find your favorite, download a bid form, and you just may win a new baby to snuggle with by the fire while helping to fight cancer. And remember: You don't have to pick up after a plastic pooch.
