Abstract: A self contained multiple color writing pen has a single writing tip for dispensing a user selectable variable color ink to paper or other surfaces from an internal mixing chamber. Several internal ink reservoirs each having a different color ink, supply their ink to the mixing chamber. A user may easily change the selectable writing color even as he writes by manually moving a rotatable thumbwheel on the pen and the dispensed ink output changes quickly in response to such thumbwheel input. The number of colors selectable by a user is seemingly infinite and includes the entire color spectrum.

Abstract: The present invention comprises a children's copying machine for copying two- and three-dimensional objects. The copy machine includes a slidable art tray for receiving two dimensional objects and or creative drawing on an erasable surface. The art tray surface is supported on springs and depressible for further receiving three dimensional objects. Special effects are provided such as image storage into memory, combining of selected images for printing, warping of images and overlay functions. A spin tray is further incorporated into the art tray for providing rotational motion to objects during the copying process.
