The tenth dimension video - how accurate?

I stumbled over this one. It’s fascinating, but it makes a lot of assumptions about what sort of dimensions exist. It largely ignores extra spatial dimensions, for one. It might be helpful in wrapping your head round the concept, though. What do you think?

Without wanting to sound too negative, that video has been around for a while, and it’s got nothing at all to do with how anybody in physics or mathematics thinks about higher dimensions (well, I guess the first three are presented reasonably accurately). It’s a piece of free association on the concept of dimensions, something not born out of scientific study, but rather the originator’s own, idiosyncratic ideas – which is me trying to politely say it’s just a bunch of made up crap.

Here are two previous threads from this board about this video:

Explaining multiple dimensions (February '07)
Physics expertise in the 10th dimension (June '10)

The video remains as misguided as it was back then.

Thanks, I suspected perhaps it was a bit off, but i seem to have blotched the search.
