There is a very nice, very accessible series of topology talks he did here : https://youtube.com/playlist?list=PLTBqohhFNBE_09L0i-lf3fYXF...

Very early on he covers Möbius Strips and Klein Bottles (what most amateur mathematicians want to hear when they go to a topology video) and later on he touches on how Brouwer’s Fixed Point theorem relates to Nash Equilibriums

I’ve tried to learn topology several times and was bogged down in definitions of open and closed (and of course “clopen” sets) every time. His lectures were very refreshing.
