Want to add a subtle touch of geek to your bedroom? Add a pixelated life bar inspired by Legend of Zelda! These 8-bit hearts were affixed to a wood headboard with screws. You start with a pattern of the hearts, then carefully use a jigsaw to cut them out of poplar. Add paint and tada! If you want bonus points, you could figure out how to light them with LEDs and then have them power up depending on how long the bed is occupied. The more you sleep, the healthier you get.
