this is just a machine where you spin different dimensions around. they are all squares/cubes. 0D - there are no dimensions 1D - there is a line, but you cannot see the spin 2D - a square that rotates 3D - a cube that rotates 4D - the next dimension after this world, the farthest imaginable dimension, makes absolutely no sense 5D - how is this far imaginable? two dimensions after this world!!! ?
