I love this soft circuit voodoo doll design that Catarina Mota and Raphael Abrams came up with for a class at NYC Resistor. Stabbing the little creature with a needle creates a short circuit between two sheets of conductive spandex, which act as a switch to turn on the LED lights. It’s a really simple idea, but produces a wonderful effect. I want to make one!
