Why stop at having a shiny red nose when you can have one that blinks, too, and no hangover the next morning? Engineer and amateur-jewelry-maker Jerry created a nifty little holiday stickpin featuring Rudolph the red-nose reindeer. His low-tech invention involves wiring a low-voltage blinking LED to a 3V battery using pieces from a metal paper clip, then attaching the components to a stickpin. Wear it to your next holiday event, and we guarantee you'll be the toast of the town!
