I came across this on Hackster.io the other day. Kitty used the pattern recognition ability of the Arduino 101 Powered by the Intel Curie to recognize different gestures. Each gesture was linked to a specific constellation pattern. She embedded Adafruit NeoPixels into her dress and arranged them so that they would light up in each constellation pattern. After a bit of machine training and a little programming, Kitty put together a really cool sparkly and totally tech-ed out dress. Check out her project in more detail over at Hackster.io on her product page.
