Shape changing Tangram Organizer with secret compartment

Inspiration for the storage cum decoration organizer has been taken from the Chinese puzzle, Tangram made of seven pieces (one parallelogram, one square, and five triangles) that can be arranged to match particular designs.

The Tangram (Chinese game meaning "seven boards of skill") is a dissection puzzle consisting of seven flat shapes, called tans, which are put together to form shapes. The objective of the puzzle is to form a specific shape (given only an outline or silhouette) using all seven pieces, which may not overlap.

Pieces:
Choosing a unit of measurement so that the seven pieces can be assembled to form a square of side one unit and having area one square unit, the seven pieces are:
• 2 large right triangles 
• 1 medium right triangle 
• 2 small right triangle
• 1 square 
• 1 parallelogram 

Of these seven pieces, the parallelogram is unique in that it has no reflection symmetry but only rotational symmetry, and so its mirror image can be obtained only by flipping it over. Thus, it is the only piece that may need to be flipped when forming certain shapes.

Step 1: Material required

Picture of Material required
For making this interesting decoration piece, which also doubles up as a shelf for storage and organisation, one can use any material (which can take weight, if it's for storage purpose).
I have used thick white cardboard. And for attaching the pieces together, one can use nut bolts and shafts (like shown in the picture).
I have made the shafts with the same cardboard (you can also try finding them in the market, if you don't want to make them). I've made the shafts by cutting the cardboard in these shapes and punching both the corners (easy and quick)!

Step 2: How to make these shapes?

Picture of How to make these shapes?
The attached picture clearly explains how these shapes can be made exactly.
Once you've cut the pieces, single punch the corners of all. This will help later for fixing them together!

If you had a piece of metal hidden benind the wall then by glueing large neosomethingiam magnets to the back of them then they could be easier to rearange.

Yes! That can be one interseting way of putting them up. Thanks :)

I have so been wanting to make these for years! But how much weight can these realistically hold?

I have seen these others and been wanting to make some like them (not being able to afford the ridiculous prices I have seen).

Hi SantaB
That depends on the material you are using. If you want a highly durable one, you can use wood (ply board). Mine is made out of cardboard, and can hold a couple of books and other stuff!
Also, it wouldn't cost you much, just a little time consuming!

Brilliant idea! My daughter and I love these puzzles. What a great concept for a 3D piece. Just initially, I can envision boxes made from varied hard wood panels. Your attachment is clever. Depending in the material used, I could see magnetic strips or Velcro as possible ways to attach the boxes. I'm sure there are many other ideas about that. The colored illustrations really bring the otherwise stark single color of the usual puzzle pieces to life. You should experiment more. You might have come up with a catchy marketable idea. Thanks for sharing!

Thans alot MarkML. I love this puzzle too, that's what made me come up with this organizer! The attachment can be done with n number of ways, depending on material being used and the purpose one is going to use it for.
I'd love to see your's too if you are planning to make one :)
