I've always thought of baby mobiles as colorful and whimsical things parents put above their children's cribs to keep them calm and entertained, not a means of scaring a child into worrying about aliens. The Space Invaders mobile, created by Chicago artist pixelparty turns the usually innocent mobile into a retro geek (and slightly creepy) art piece. It's made from wool felt, dowels and cord and features nine individual “invaders” as well as one “laser base." It costs $70 at Etsy. Is this the perfect gift for a gamer's baby, or too geeky to put in a child's room?
