Mario and his sibling, Luigi, stole our hearts in 1985, and they’ve kept them hidden under a random turtle shell ever since. Don’t try to find the shell–just give in to the addiction with this Interactive 8-bit Question Block Lamp ($75). Made of laser-cut plexiglass and lit from inside by energy-efficient LEDs, this retro piece will take you back to the battle against Bowser with its touch-activated sound effects. One tap (or head bonk) and the light and classic coin noise will emerge. Plus you don’t even have to blow on the light to get it to work.
