I love Matt Parker's take on the fourth dimension: see for instance this one-hour long but very enjoyable talk for general audiences at the Royal Institution: [VIDEO] (Things to See and Hear in the Fourth Dimension) If you know German, then you might like this talk as well: [LINK] (The curious world of four-dimensional geometry)
Read original comment ↗For anybody whom might be interested in "what a 4D cube might look like..." [VIDEO] The entire video in mesmerizing -- one of the coolest party tricks I've learned is the double-twisted morbius strip dissection.
