Reality, like Truth and Beauty, is largely in the Eye (I) of the one (1) beholding it.
Don’t believe me?
ALL gold and browny-gold lines in this pic are of EXACTLY the same length in the REAL world… (Yes – the diagonal and the sides are the SAME length! As are all horizontal and vertical lines.)
How does your reality stack up to this one?
Which perspective you take/choose to view it from is the key.
I designed and am building this object in 3D.
Can anyone figure out how to describe the shape?
Bonus points if you can describe it exactly in just 7 words. (Ask in comment for the answer.)
