Recommended as an enjoyable, accessible talk for building intuition about higher dimensions.
Matt Parker gives a hands-on Royal Institution talk on how four-dimensional shapes appear in a 3D world, with props like straw frames, Mobius strips and a knitted hat. It is a playful general-audience tour of the fourth dimension.

For anybody whom might be interested in "what a 4D cube might look like..." [this video] The entire video in mesmerizing -- one of the coolest party tricks I've learned is the double-twisted morbius strip dissection.
