We have used a metal sheet with pin holes drilled in two positions so that two persons can view at the same time. Frosted plastic sheet is mounted in between clear sheets for the hand held screen. We have used the rear site to exhibit a few optical illusions as a bonus. To give stability for the Exhibit we have made a ballast box. We have also provided castor wheels with locks for easy alignment.
