Bram's Fortress
Click a thumbnail to see its larger version and description.
Eight cubes which outwards going faces twist connected to each other in sets of four faces.

This puzzle can be considered as an eightfold implementation of the Fused Cube (a cube with only 3 twistable sides) with an additional connection between six sets of four sides. This connection guarantees that all four single faces pointing in the same direction twist together.
This is the result of an idea Bram Cohen mentioned in 2009. Oskar took up the challenge but after three prototypes he had to give up.
The third prototype which is shown in the images here works but needs way to much force and manual alignment to be played with.
The number of permutations of the total puzzle is the 8th power of the FusedCube's size divided by 16. This equals to 44970586918084054475602454040030532394593344045352013301519502539635304443033153306864467165839360000000000000000 permutations.
