Think "outside the box"..........how cool would these be for a Steam Punk or Sci Fi sculpture? (they would make FANTASTIC eyes for a Robot or even the muzzle of a Laser Blaster - just imagine if they could be powered up WOW!). Would also be ideal for TV film set & prop or as Steam Punk / Industrial Decor.........whatever use you may have for them, they are way too good to just throw into land Fill!
