                    Plot twist! The dancer isn't spinning at all, but rather the camera is spinning around her!

                      I'm sure you work hard to make this video but man I get annoyed by your fake ass dramatics, its not funny. Your voice just doesn't work well with me, its as if I'm hearing a really fake parody of comedian telling a joke. Its like Ryan's character, Regina(from Nigahiga) except that one is funny despite being annoying.

                                      Waaaait, if the camera looks down 45 degrees, then... the camera in the mirror must look at a different narrower angle because of the extra distance in mirror-space to the mirror-object. OK, you know what I mean, don´t you.? Easy to explain with a drawing, but youtube comments don´t allow for that yet... So mirror-space will have to do..
                                      It would still work quite well, but it wouldn´t be the nice point-symmetrical S shape you showed in the explanatory animation and you would have found that out, making the 3D model, so... What´s going on there? Are YOU misrepresenting your video-effects??
                                      Dumbing it down for us?
                                      And after that mock outrage, I am more comfortable asking a real question...
                                      I don´t understand the bit about the focal length, could you explain that? Doesn´t that have to do with things going out of focus? How could tweaking a shape help in that regard? Or do you mean the focal length that changes the intensity of the perspective effect like with a wide angle lens? Is that the same thing? But you already said you had to tweak for perspective, didn´t you?
                                      In short: Huh?

                                                Sorry to ruin the party, but you take a good idea, of explaining visual illusions, and destroy any chance to see it to the end.
                                                You are too NOISY, too FAST, awful MUSIC, too COMPLICATED, too many GRAPHIC effects, and a general feeling of throwing your watchers into a huge BLENDER!!
                                                Man!! Relax!! Hold your horses!! Press the middle pedal!!
                                                It is a scientific category video after all, can you be more quiet please.

                                                                In 3:02 you say that changing the lens' field of view could ruin the trick. That's wrong.
                                                                Changing the focal length WILL NOT change the perspective of a scene (a.k.a. point of view, a.k.a. the sizes and positions of objects relative to one another). Moving the camera's position is the only way to change the perspective. The lens' zoom itself only works as an ordinary crop*.

                                                                Of course, each camera position "asks" for a proper focal length (and vice-versa) in order to properly frame your subject. That's why this is a very common misconception.
                                                                Dolly zoom movie scenes are excelent demonstrations of what changes of perspective look like.

                                                                Best wishes!

                                                                * Yes, there's also possible barrel and pincushion distortion in every lens. But this has nothing to do with perspective, therefore it's irrelevant to the argument.
