Joshua Madara over at hyperRitual has some laser-cut acrylic Chaos Ex Machina Pendants which may be of interest.
“Show your love for Chaos, machines, or Chaotic machines with these laser-cut, black acrylic pendants featuring the symbol of Chaos cut out from the center of a gear. Each pendant measures two inches wide and has a matte finish on one side (the unfinished side is glossy). Each includes a jump ring to attach the pendant to a necklace chain or cord (not included). Each also comes with the Chaos symbol that has been cut from its center, for you to do with as you like (I keep mine on my altar).” [via]
