  • Question
    Can you do this with any picture or device?
    Community Answer
    With any device yes, but not with any picture. My favorite picture is of a hummingbird, I just Google "hummingbird hologram 3D".
  • Question
    How do I increase the scale of the illusion?
    Community Answer
    You would have to make bigger-sized pieces of the CD templates, so instead of using centimeters, use inches.
  • Question
    Can I make this into a triangular shape instead of rhombus?
    Community Answer
    First of all, the figure above is a trapezoid, not a rhombus. Second, you cannot make it into a triangle because then you wouldn't be able to make it stand.
  • Question
    Why does it need to be cut into a rhombus shape to make a pyramid? Why can't it be a cube?
    Community Answer
    The rhombus shape reflects the light of the phone at an angle; a cube doesn't let the light bounce off it right.
  • Question
    Can I use glass instead of a CD case?
    Community Answer
    No. Glass would be too thick for this application.
  • Question
    Can I use a plastic box instead of a CD case?
    Community Answer
    If it's plastic and it looks like the image at the top, then yes. But if the plastic is too thick, the light may not bend well.
  • Question
    Can I use a CD instead of using a CD case?
    Community Answer
    CDs themselves aren't transparent, so that wouldn't work. A CD case or other acrylic sheets of plastic must be transparent for them to be used for this project.
  • Question
    Can't the base be triangular rather than square, like a triangular pyramid?
    Community Answer
    The top has to be square-shaped in order for the pyramid to sit on top of the smartphone. If it had a pointy top, then it would just topple of off the smartphone or tablet.
  • Question
    Can I use an acrylic sheet to make a holographic illusion pyramid?
    Community Answer
    Yes. What I used personally was an acrylic sheet of 0.5 mm, the plastic that comes on top of the square-shaped packaging used for transporting cakes.
  • Question
    How tall can I make my holographic illusion pyramid?
    Community Answer
    There shouldn't be a set size. you can make it as big as you want, but you should realize that the height of the rhombus to the size of the tip will affect the height of you picture, so I would use equivalent ratios.
  • Question
    How do I know if my holographic illusion pyramid should be big?
    Community Answer
    First, you want the ratio of the size to the tip to be the same as shown above. You also want the tip to fit in the middle of the phone without touching the sides of the pictures.
  • Question
    What can be a substitute to the CD cover?
    Community Answer
    Clear plastic plates work well, or you can use any clear, sturdy plastic food packaging.
