3D Booklet is a nice 3D design visualization software on AIR. Contains 21 pages of 3D fun - this booklet shows planes, boats, toys and other objects colored by your design. Select from a variety of colors or make your own to paint the objects - your changes will be saved. Press the eye icon to see the pages displayed as a 3D object. Click and drag to rotate the object around, or move the object.
Fun for all ages but requires some skill for coloring the more detailed pages. Hint: zoom in on the smaller parts and rotate them to color more easily.
