Ok, this writer is just going to admit it: in addition to goofy USB items and off-kilter (or useful) iPod docks, she has developed an obsession with anything recently retro, waxing nostalgic about doo-dads that remind her of the 70s or 80s.  Case in point: Rockza’s Space Invaders Bag, made of PVC (translation: faux leather), and decorated with rows of the scurrying aliens. Oddly missing are the four protective “shelter blocks” and cannon, but we’ll let it go.  Unfortunately, the bag is only available in Korea for 42,000 Korean Won ($45 USD). But let’s hope the trend comes stateside, as we think a Centipede version would look really cool, in a geeky sort of way.
