www.thetruesize.com is a fun interactive website for seeing how Mercator maps lie.
What’s your preferred projection?
To say that Mercator “lies” is to misrepresent the complications of projecting a 3 dimensional object onto a 2 dimensional surface. All projections “lie” in this sense because they’re simplifications of reality - that’s what a map is.
this video is based on the comic: it’s an animation on how each projection would change when shifted.
