making slides to show on wall

Could you expand on your question a bit? Do you have a projector and a screen?
Are you having trouble making the slides project to the screen? Just normal
slides can be shown on a screen and even on a white wall sometimes, though they
may not be bright and crisp when shown on a wall. It sounds like there is more
to your question than you have provided.
 
Several suggestions Bob,

Start by setting the show at 16:9 aspect ratio (File/Page Setup/16 width X 9
Height) or even 32:9.

You can now project your slides higher on the wall so the audience doesn't
have to stretch to see around heads in front of them.

Then create all slides on a black background. Projectors don't project
black, so a blank screen on the wall will be the natural wall color at
ambient light level. Use bright color text, white, lime green, any of those
hot colors you might like. I would avoid the yellow.

Forget any margins for text or graphics because projection using a black
background should not create a frame (if your projector has a high contrast
ratio)
so you can now utilize up to 15% more of your slide, go right to the edge,
or move your projector closer to the wall for a 15% brighter projection.The
perceived screen size is the entire wall.

Treat your text or graphics as layered objects and cross path animate in
front and behind each layer for dramatic presentations.

White walls are great but grey are best, and all the way to black, as long
as its flat paint. Any texture or imperfections will show up for sure.
A picture of a white dove projected onto a green wall will create a light
green dove, unless you can really overpower it with a high lumen projector.
There are commercial wall paints for projection, Goo System acrylics comes
to mind, try a Goggle search to find them.

It all comes down to understanding the limitations of projection and taking
your creativity right to the very edge for a memorable presentation.

Okay on the count of three everybody throw your screens out! (just kidding)
