There are two surfaces at play here - the screen and the transparency sheet. The transparency sheet is fixed at an angle of around 45 degrees to the screen. The screen is illuminated, which means that it is transmitting light. Part of this light gets reflected by the inclined transparency sheet, and an image of the reflection is produced. Now, we place four such sheets symmetrically so that we get an image on all four sides of the screen. And finally, we play a specially designed video for this task. The video has four separate windows arranged symmetrically corresponding to the transparency sheets. This is how we give volume to our holographic projection.){kind=spacer}
