LEGO Rubik’s Cube

"The idea of building a working Rubik Cube has always appealed. Here the
challenge is to create a mechanical device that has a number of degrees
of freedom about a central point. It’s not easy! The cube consists of 12
edge pieces, 8 corner pieces and one central piece. All of these have to
be interlocking, yet still be able to rotate about any axis at any time
in any direction! And all this with a basic square block! Thankfully
LEGO has been kind and the ratio of 5 bricks to 6 studs allows us to
create a genuine cube structure.”
