I first discovered this about three months ago in a reddit comment under 'r/geography', and I still, from time to time, use it and enjoy it. Back then, I posted it here in HN, but zero traction!
Anyway, for those interested in previous discussions, here we are:

But why do countries rotate to the left as you drag them north and rotate to the right as you drag them south?
The largest surprise for me (besides the massive size of Africa and South America of course) was that Australia has roughly the same area as the entire US. Somehow I had always imagined it smaller.
That's how I proved that the actual size of Australia is approximately 90% of the area of the globe. Who knew the mercator projection could be so confusing! :)
It turns out that even when put in the middle of Africa, Russia is still massive. And even without the projection, Greenland is not small either, which, in a sense, makes Denmark the largest European country by far.
