Here are images that I created with a Blender, a free 3-D modeling tool. For a full-size view of the picture, just click on it.
This one was easier than it looks. I just made one die and duplicated it.
This one was made from several files. The wheels, seats, and missile
launcher were all made separately then imported into the main picture.
Here is a little house with a white picket fence. The tricky part was
building the fence since I had to make one picket and duplicate it
many times. After I build the front fence I was able to duplicate the
whole thing to make the back and sides.
