I'm not usually one for freaking out over Etsy products, but I stumbled onto this page this morning and had to share. What you're looking at is a Super Mario Coin Block hanging lamp, complete with sound effects and a touch-senstive underside. The price is a bit steep at $74.99, but these puppies are custom made.
The 6"x6"x6" cube is made of laser-cut plexiglass and uses LED bulbs to conserve energy. It dangles from its 11-foot power cord, so you'll need a hook to hang it from and a convenient power outlet. The coolest part though? There are sound effects. Turn the light on and you'll hear the SMB coin 'ding'; every eighth time you turn it on, you'll get the 1-UP sound. Badass.
