Concluding a marathon day at the Greener Gadgets Conference, Allan Chochinov of Core77 took to the stage along with panelist/judges Ryan Block from Engadget, Valerie Casey of The Designers Accord and IDEO, and Jill Fehrenbacher of Inhabit (and Greener Gadgets). Following a whirlwind tour of dozens of notable entries, the panel discussed their top ten, then turned the final vote over the audience in true clap-o-meter style, who's first place choice might have signaled a slight backlash against gadgets--after a whole day of 'em. It was a great session, and we were thrilled with the results. Core77 wants to thank everyone who entered the competition, everyone who supported it, and everyone who made an attempt to create some positive change.
