3b1b uses a python library for creating those videos. [LINK] As far as a math educator/communicator, one of my favorite videos of his is the video on the monster. [this video] Also since we're talking about powerpoint here you should probably see this Matt Parker video about excel being used in ways it shouldn't maybe? [LINK]
