I was playing around with the 4D Building Blocks (still trying to totally figure it out) and I was rotating the perspective (I believe thats the right word to describe it) to see the two different lines (red and blue) to line up to see the building blocks different ways. Now I was wondering since x and y are interchangeable since both could be either (yin yang situation, pretty much) so I was wondering could z and w become interchangeable; however, this program contradicts this as where if you line up x on this game you line up y but if you line up z, you don't line up w and vice versa. So I just wondered if anyone had any clarification to this question?
And I'm sorry if I have any improper analogies and/or theories, but please keep in mind that I'm only in 8th grade and all my teachers this year taught me nothing near these fields of science and mathematics.
