We're not so into over-the-top themed rooms. But if you're going to go with a kitschy gamer-inspired home, we'd rather see it done with subtle and still cool pieces like this Space Invaders lamp shade...
...and let's skip the mushroom lamps for this square, black Space Invaders lamp shade.
Featuring a few of your favorite S.I. critters in green on each side of this wire-and-fabric lamp shade, you'll stay in grown-up territory while still keeping a finger on the pulse of your childhood.
It's available from Meninos for $60 in your choice of table-top or ceiling-hanging shades.
