Photo-chromic doll playsets, photo-chromic toy vehicle playsets and activation light projectors

Abstract

In one embodiment of the invention, photo-chromic doll playsets are disclosed. A photo-chromic doll playset includes a doll having a substrate; a photo-chromic material applied to the substrate; a light pen to selectively apply a tightly focused activating light output on the photo-chromic material to create narrow lines of activated photo-chromic material. In response to the activating light, the activated photo-chromic material temporarily transforms from a first color to a second color for a period of time before gradually decaying back to the first color.
