Introduction: Secret Image Shadow & Light Sculpture

This hanging light sculpture looks interesting from any angle, and makes nice shadows. But from one precise viewing point, a secret image is revealed! You can build a sculpture like this from any number of different materials.

Step 1: Select Your Materials

I built this sculpture using scrap plastic triangles and this brass rod. Any number of other materials could be used. You just need some stiff bendable wire (brass or copper around 1-2mm diameter are good choices) and a lot of chunks of material you can easily fasten the wire to.

Step 2: Make Attachment Points in the Chunks of Material

here, I laser-cut small holes in the plastic triangles. If using wood or metal pieces, you can just drill holes. We'll be inserting the wire into the holes so it fits tightly. As an alternative, you could not bother with holes and glue, solder or weld the wire to the pieces.

Step 3: Assemble the Sculpture

i did not plan this sculpture out much. I knew what secret shape I was making, and then I just started sticking together wire and plastic and bending it around.

Draw the secret shape you are making on a piece of paper, and tape that paper to the wall. While you are assembling, you will be constantly holding up the sculpture at arm's length and viewing against the template on the wall. then bend any piece which is out of position to fit the template.

Wear latex gloves to keep fingerprints off the pieces, otherwise you will need to clean afterwards with alcohol.

After assembly, I put a little glue on a lot of the connections to prevent shifting. Or, you could dip the entire thing in paint.

Step 4: Hang From Ceiling and Enjoy!

    this is sooooooooooooooooooooooooooo cool!!! I <3 it, ur very creative! :D

    THNEEDLE already asked my question. how thick should it be? as in, how deep from the hidden angle should the sculpture as a whole be? oh, and how many feet/meters of wire did you use?


    it doesn't really matter.   if you are viewing it from 3 feet away while constructing, then when you shine a light at it the shadow will be best seen with the object 3 feet from a wall.  a deep object will have more parallax, and thus will be viewable from less variation in distance, but always fine from the exact distance used during construction.  the first photo is about 90 degrees rotated from the 2nd. 

     This mixed with another similar instructable will make me do a "the cake is a lie" hidden message :D

    I love this idea! This could make an awesome mothers day/valentines day gift!

    Pretty cool

    Very nice! I'm definitely going to try and make one of those when I get my own place How hard is it to get the shape right? Could you fx make a star or a flower, or would that be too difficult?

    Absolutely genius.

    So, you kind of just wing it? That is so awsome! :D
