I remember watching a youtube playlist on a video about equation of a plane and about vectors in 3D. The video was fully animated in 3D and had good sound effects too. I feel like it had a clock mascot somewhere but I could be wrong. The video was narrated by a professor.
Just to provide this question with an answer, as my suggestion was confirmed in the comments, the Youtube playlist you're looking for is Robert Ghrist's Calculus Blue Volume 1 on vectors and matrices.
