    The speaker of this video works up to the fourth dimension by starting with a 1-dimensional line on a chalkboard. He then moves to a two dimensional coordinate plane. Still working on a chalkboard, the speaker makes 3-dimensional coordinate axes. Finally, a four-dimensional model is discussed. Points and lines are used to present the fourth dimension by analogy, and some 4-dimensional objects are shown and discussed in depth.

    The animations are excellent and help make the 4th dimension a little more understandable.
