Well he didn't make much attempt to make things exciting but I'm glad I watched the whole thing. I am already familiar with tesseracts but the perspective of dimensional shadows was interesting.

oh crap, searched for tesseract and found an extremely fun animation at http://en.wikipedia.org/wiki/4th_dimension

I thought the fourth dimension is time. I'm sure there are dozens of people from the distant future observing me via remote wormhole cam at this very moment.

Maybe not in geometry but I'm pretty sure that in physics, time is the fourth dimension. Ie; "Spacetime"
