Hi everyone
I thought that I would share some of my 'Magic Folding Cubes' with you, also known as 'Photo Folding Cubes' or 'Yoshimoto Cubes'.
From left to right: Small Version, Large Version, Giant Version.
Although I came up with all of these designs independently, I have since found out that others have also made these cubes out of Technic, and my solution for the small cube is identical to the solution that others have come up with. I guess that is to be expected when designing something so small with such a limited number of pieces. (eg. see here: http://www.eurobricks.com/forum/index.php?/forums/topic/46788-build-three-lego-technic-promo-magic-cubes/)
I haven't seen anyone do the Large or Giant versions before.
The Giant version also has some extra features that the smaller ones don't. You'll have to watch the 3rd video below to see these features!
Here are some videos that I made:

And I have also uploaded the MLCad files and Inventories to Rebrickable: http://www.rebrickable.com/users/slfroden/mocs/
Lastly, I was also honoured to be blogged by the Brothers-Brick: http://www.brothers-brick.com/2017/04/30/make-lego-magic-folding-cube-just-pieces-instructions/
