Simple and beautiful LED-lit sea urchins

The Evil Mad Scientists created these awesome, dead-simple accent lights by dropping an LED clipped across a battery into a sea urchin shell from a beach shop. Windell describes the guts as a “throwie sans magnet.” I love the way these look. But I hereby pledge to dig in, with both heels, and resist the term “urchie” with all my power, unto my dying day.
