Noah Swartz writes, "Jie Qi from the MIT Media Lab and Bunnie Huang of Hacking the Xbox fame have teamed up to make LED stickers! Using adhesive copper tape you can turn any notebook into a fantastical light up circuit sketchbook. I got to play with them myself at FOO Camp and they're as easy to use as the look, and in the time since Ji and Bunnie have gone back to the lab and made a number of sensor and controller stickerss that give you loads of options of what to make. They're running a fundraiser to do a big production run of these over at Crowdsupply, and while they have funding I'm sure lots of people will be kicking themselves if they don't manage to grab some of these while they can."
