"map of NYC" does not include Staten Island. That's how we like it

This is cool, but more as a demonstration of interesting CSS techniques than optical illusions in my opinion.

Also, interestingly, I seem to be able to force myself to "see through" all of these illusions except for induced gradients, which I can't stop seeing unless I cover part of the screen.

Can someone give an example use case of this? I'm not sure I understand why a very public long string of random characters on a block chain is useful, except as a way to prove an event didn't happen prior to a certain time

Why would the author even make a point about the different seasons between hemispheres and then immediately get it wrong? He tells the reader to "reverse the seasons and add six months to the dates," but doing both of these operations cancels them out. "The summer solstice in June" becomes "the winter solstice in December," which is still the northern perspective.
