Lighting up the Walls at Night

  Wonder if this idea might work.
  Invent a paint that has a plastic or glass fibre base. The idea is that when it is painted on a wall a light source from a point can light up the paint thus illuminating the wall.
  The effect is similar to fibre optics and some plastic strands which have been shown to be able to trap and channel light shone through its cross section.
  This idea needs in-depth research but if successful the result can be most interesting.
