A puzzle origami invented by Piet Hein and diagrammed by Sebastian M. Kirsch. It’s a fun toy to kill time, I spent about 10 minutes assembling it the first time and it didn’t get any easier the second. It’s composed of 7 different pieces made out of strips that look like those in Tetris. You can also make 6 pieces which would make it easier to assemble, here’s a Soma cube with 6 modules made with Sonobe modules. If you really like this model and the strip origami is too hard you can make it out of Sonobe units which are very easy, but I doubt it will be as sturdy.
The diagrams show how to fold the basic unit, once past that you have to figure out how to fold the rest. I advise you to make the 4th piece last since it’s the most difficult one, it’s very unstable until fully assembled.
A video and pictures of the units after the break.

wow….looks fun! I have a math book, so I can just cut it according to the lines hehe….. Thanks very much:-)
Wow, it looks great! I’ve been trying to find how to make one of these, but then I gave up. I can’t wait to start this now.
You rock.All of these are awesome!!!!You should try a butterfly ball.
Hi , i was wondering where do you get these types of music?
@Wei: I let Winamp rip the songs off an ambient Internet radio channel with Streamripper.
i wonder how much time it needed
i luv the tetris look
Like you said for the sonobe units, Karl, the pieces are sturdy, but the edges aren’t sharp and some of the modules keep slipping out, so I suggest you do strip version instead of sonobe version.
this is an awesome website. you have many of the designs ive been looking for a long time. i have one request though. its called the “menger sponge” and it doesnt look too hard. if you could show a vid on it, that’d be great.
