Mr. ArduinoFun has posted a really great tutorial for the electronic seamstress on Instructables. The concept, based Ethan Dicks from theFusefactory.org's emergent Sheep Sculpture project, is a scarf that detects when you are near your loved one.
It shines BLUE when you are lonely and shines RED when they are near. Awe! This project is for those who are familiar with programming a small mini-computing device called the Arduino, but he does give the code if you don't know how to program.
Please go check out the instructable, this one has everything.
