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
See also: The monster: ▶ this video Ideal packing of squares (some are elegant, 17 is not) link The 4 color theorem was solved by reducing it down to 633 cases and just using a computer to find a coloring for each case: link
As a noob I'd say this also falls into that category: [0]. Who knows, if enough people ask about it on his reddit (topic requests) :) : [1] [0] ▶ this video [1] link
