There is a similar thing going on with one type of treatment for amputees that suffer from phantom pain in the missing limb. It uses a box and a mirror positioned such that the subject can see a reflection of their existing arm/hand but the mirror spatially locates it to where their missing arm/hand would be.

It isn't a sure-fire cure, but apparently it offers enough relief to enough sufferers.
