     • 3D Printer
       • This does exactly the same as a normal printer just outputting 3D images
     • This outputs ink onto a sheet of paper equivalent to the formation of the pixels on the scren
   • Tablet
   • Fan
     • This propels warm or cool air towards a specific target to change its temperature
   • Television
     • This outputs pixels which form an image
   • Headphones
