This week, I’m going to introduce some my
favorite design of Oskar van deventer.
First, mixup.
Take 3*3*3 as an example. if it is a mixup
cube, you will see that the rate of the cubies’ edges is 1: sqrt(2): 1 . And
with special magical structure, when you twist the second lawyer for 45
degrees, you can still twist the cube. It means that the position of the center
and the edge cubies can be switched. There are many different kind of mix-up
cubes. mixup3*3*3 is just the basic one.

Second, gear cube.
As its name suggests, it is a cube combined
with gears. The most simple is 3*3*3 gear cube I. all of its cubies are substitutes
by gears, which makes all of the neighboring lawyer are related. So, when
you twist the first lawyer for 180 degrees with the bottom lawyer fixed, the
second lawyer will be twisted for 90 degrees at the same time.
