some videos on non-Euclidean geometry

This post is an answer to those who have asked me - do you have anything on YouTube we can watch? The answer is - no, I do not have anything on YouTube but there are some videos of me available:
this is by Sciencentral Extreme Knitting
then there is in series Mathematics Illuminated Unit 8 Geometries beyond Euclid
the most recent one Talks from the Yarniverse

This time I wanted to point out other video resources about non-Euclidean geometries or related topics.

History of Non-Euclidean Geometry by Jeremy Gray from Open University class:

From the series of Great Courses on You Tube there is a lecture by Prof. Judith Grabiner on the history of non-Euclidean geometry:
part 1

part 2

part 3
in this part I disagree about some of the geometric explanations - but I  guess this lecture has been recorded a while ago - straight line is the shortest distance between two points ONLY in Euclidean geometry, also hyperbolic plane IS NOT an extension of saddle surface; etc :

part 4

Amber Case gives her introduction in Hyperbolic Geometry on much lighter note:

Not the Knot should be filed under "movie classics":

make sure not to miss the part 2:

great video on Poincare Conjucture:

most recent one is the talk of Vi Hart at Joint Math Meetings  last Saturday in New Orleans:

well, there are more - just search for them online.... :-)
