Devoted geeksugar reader calamari seemed rather intrigued by these bright yellow and pink Space Invader necklaces, noting they are "gosh darn cute." I have to agree with him there. The Space Invaders video game was initially released in its native Japan in 1978, but still tops many lists as one of the most influential video games ever created. What better way to commemorate the game and our love for geek jewelry than with colorful, feminine Invaders of our own? The piece costs about $30.
