As my friends will attest, I am somewhat math-impaired. It just doesn't come naturally to me for some reason. So perhaps that's why I am fascinated when I come across something like the following video, which explains Mobeus Transformations. Geometry was always easiest for me to understand in school because it's visual, but a concept like this is still pretty intense. Fortunately, this video is anything but intense.
So, although you didn't expect a math lesson when you came here, I think you'll enjoy it!
