Video Credit: Jonathan M. Sullivan-Wood

Make sure the five rays coming out of the projector are parallel. Place a plano-convex or plano-concave lens with the middle ray going through the center of the lens. Accessories are available so that you can do a double convex or double concave lens if desired. The focal point may not be exact, but will be close enough for people to get the idea.
