Copy the Hypercube, paste it on top of the original, but a bit offset and then connect the new corners to the old ones. Congrats, heres your 5-D Ultracube! Repeat for more geometric insanity!
the tags on this save gave me cancer.
kinda looks like a crystal :D
Time isn't necessarily the fourth dimension. We think of it as the fourth simply because we identifed X, Y and Z first, then decided that T was another expression of the same thing (hence 'space-time'). Then string theorists and other demented genii invented lots more, which we assume exist just because if they don't, certain other theories don't make sense.
