A photo-chromic drawing toy comprising:
- a photo-chromic drawing tablet, the photo-chromic drawing tablet including a housing with a photo-chromic drawing slate mounted therein, the photo-chromic drawing slate including one or more layers of photo-chromic material applied to a substrate;
- a light pen, the light pen to selectively apply an activating light source on a portion of the photo-chromic drawing slate;
- and
- wherein a portion of the one or more layers of photo-chromic material is temporarily transformed from an inactive state to an active state in response to the activating light source.
A photo-chromic toy comprising:
- a substrate provided on a three dimensional structure or a portion thereof;
- one or more layers of photo-chromic material applied to the substrate;
- a light pen, the light pen to selectively shine an activating light on a portion of the one or more layers of photo-chromic material;
- and
- wherein the color of the activated portion of the one or more layers of photo-chromic material is temporarily changed in response to the activating light.
A method comprising:
- providing a substrate with one or more layers of photo-chromic material applied thereto;
- selectively shining a hand held activating light source towards the photo-chromic material to activate a portion thereof;
- and
- wherein the activated portion of the one or more layers of photo-chromic material is temporarily transformed from an inactive state to an active state in response to the activating light source.
