Really neat
You have to buy one of the Electric Imp embedded computers and maybe a breakout board to solder some components to (I built a wifi thermometer), and then you use this nifty app to "blink" you wifi configuration details to the chip - and off you go. I had a few issues with ambient light (put your hand over the card and phone), but that's no fault if this app. It's a nifty low cost solution to bootstrapping an embedded device. Top marks to the dev's for dreaming this up!
