How wonderful that we have met with a paradox. Now we have some hope of making progress — Niels Bohr
I love paradoxes, visual, verbal, mathematical, logical… Gaurav Bhatnagar and I wrote a two articles on visual and mathematical paradoxes which had many new and interesting designs. This one, however, was created many years ago. I like the manner in which the P transforms into an X when rotated 180 degrees. The solution I came up with is pretty unique and non-standard.
