Introduction: Magic Dice Illusion - Download and Make for Free!

An intriguing optical illusion for everyone to download and make for free.
This model was originally published on www.robives.com
There are no moving parts in the model but as you move the model side to side the dice appear to float around above the baseboard. Weird!
Download the parts from the link and make your own Magic Dice Illusion!

Step 1:

Print the two pages onto thin card (230 gsm / 67lb) Score along the dotted and dashed lines then carefully cut out the parts.

Step 2: Making the Base

Glue together the base folding the flaps on the sides to make right angled triangle tubes. Glue the two stiffeners into place across the the back of the base.

Step 3: The Dice

The secret of the illusion is that the dice are actually assembled inside out. Glue together the two dice inside out as shown above.

Step 4:

Glue together the two stands.
Glue the stands to the dice corners as shown in the second picture.

Step 5: Completing the Model.

Glue the stands to the base and you're done.
Hold the base at arm's length, close one eye and gently rock the board side to side, blink your open eye a couple of time and be amazed as the hollow dice suddenly appears to be solid! Magic!

Step 6: The Reveal.

That's magic!

Awesome! I had no clue how this is possible until you revealed the trick in the video.

Made this and would have to disagree that it works well in a camera but not in real life. The trick is to stand at a point where your eyes stop interpreting it by parallax (about 4 feet in my case), then move side to side or up and down. Works brilliantly, even with both eyes.

It also works best in natural light. Using a ceiling light is less due to the shadow effect from having a light above on the inverted shape looking wrong. Best position is on the opposite side of a room from a window when it works perfectly. In fact, it's interesting to walk forward and watch at the point where your brain stops seeing it as a solid 3D object but as the inverted shape it really is.

Not sure from your comment if you actually made this, Electruk, but if you didn't I'd suggest you do. It's quick and easy and you might be pleasantly surprised.

Like many optical illusions, these work best with cameras, rather than in real life. The Ames window illusion doesn't work in real life, only on camera.

Many Escheresque illusions only work on camera. The parallax of 2 eyes ruins the effect.

It works well if you close one eye.

Just made this and it's really cool! Well Done! Reminds me of the 3d pictures you have to stare at it for a moment and it comes alive.

that is wicked cool! Just made one and it took a minute for me t see the illusion. You gotta kinda focus like you are looking through it like with a Magic Eye image. I'm going to do this with my teens at work. Thanks.

Thanks! The illusion works best is you close one eye. Blink your open a couple of times and the illusion will suddenly jump into view.
I'm going to add these instructions to the 'ible.
