Are you really CGP Grey? If so, thank you for your high quality videos! (Science) educators like you make YouTube and the internet a better place :)
(Ooh, I had a quick question if you don't mind - how did you get into animating the videos in the beginning? I'm also hoping to make sciencey/educational/technical videos on YouTube but I don't have any animation/software experience. Right now I'm just planning to draw static images/diagrams on my iPad and use that for the video, like a slideshow.)
