Everybody's played Space Invaders at least once in their life. But you'd have to be pretty hard core about it to dare adorn your front porch with the Back Off Door Mat ($110).

The Back Off Door Mat, designed by French designers La Tête Au Cube, uses AA batteries to power LEDs that display those evil aliens we've all come to hate. The mat, made out of rubberized plastic, is supposedly durable enough to withstand hours of alien-stomping with no fear of breakage. Dorky as it is, if you already have a 100-inch arcade machine and VirtuSphere, you may as well go all the way, cool guy. — Nino Marchetti
