Hello world!
I'm talking about using billboards to display images in Alice3.
I have a scene with an alien and UFO.
The story I want to tell has the alien and the UFO landing in Paris.
We don't have anything in Alice that really looks like Paris.
So what I'm going to do, I want shapes, 
and I'm going to put a billboard in my scene.
One of the billboards properties is to import an image.
When I select that I have a number of pictures that I have downloaded
one of them is Paris, so I'm going to click Paris.

You can see my picture of Paris here
but it's really tiny, what I want to do is move it back
behind the UFO and then resize it to make it really, really, really big.
Maybe I need to get the UFO and bring it forward.
I may have to resize that.
Let's make that fairly small, and then bring it forward just a little bit, 
and bring that over.

I want my image of Paris... let's adjust the camera angle a bit.
I can make Paris bigger again so that it's going to fill the whole screen.
Let me select the alien this way and move him. 
This is not a 3D image and we cannot move our spaceship 
around the Eiffel tower and things like that.
We're just using that as a background.
There we go. The aliens have landed in Paris!
