Air Glow

An introduction to a pen that writes in mid air. Imagine constructive interference of a few focused electromagnetic wave sources on a small volume the size of a marble a few feet in front of your face. The diatomic nitrogen within this volume may be excited to glow, to emit visible light in all directions. In order for this to happen one must fiddle with this external time dependent field. This is purely gedanken, however, very possible in the near future. Possible issues:

  1. Field energy density nodes not being the right size
  2. Sources too difficult to converge to only local small points
  3. Diatomic Nitrogen or Oxygen spectrum not near visible ranges
