How do I make shadows? How do I make my wall texture more visible? Here's

Have a read of the docs on what area_lights do.
At the moment you havn't got anything that would cast
much of a shadow, only the walls and the floor. Really
you want the walls and floor to be illuminated.
Remove the area light code from your light and put a
sperer at <0,2,0> and you should see it's shadow.
Hope some of that helps.
PS: I always use MidnightBlue for my background, but I suppose it's
a matter of taste.

The main problem you are having here is that your walls are transparent.
This can be seen by changing the background color.
The easiest way of defining an opaque color is to use: rgb <1,1,1> (or
whatever values between 0 and 1 inside the vector).
I revised your code a bit and perhaps this is more what you were looking
for?

Do I need to inverse the ceiling? And how do I shorten the shadows? here's
the code:

}
// Right Wall
box{

Don't know what's going on that you might need to inverse the ceiling, no
media in there and normals shouldn't matter.
To shorten shadows you just need to narrow the area light axis lengths
(<8,0,0>,<0,0,8> smaller numbers there) or move the light farther away if
you can. In v3.5 you can also use the parallel keyword in the light which
will shorten shadows in a way too.
Looks to me like you have the light far outside the room walls.
Don't scale by zero, BTW. Use a very small number if you must but zero gets
changed to 1 and causes a warning message.
