There's a subtle flaw hidden in the X logo. It's a subtle problem that's usually hard to notice.
Musk asked for a new logo to replace Twitter overnight, and X's followers suggested an image made from Unicode characters. Musk accepted, and Twitter changed to a logo that doesn't come to mind at all. Since then, it has been updated with a background that has a worn-out, dirty, grunge effect, reflecting Elon Musk's personal taste.
Design YouTuber Will Patersondid not pass by the somewhat uncomfortable X logo. The diagonal lines of the X logo are physically straight diagonal lines that overlap well, but to the human eye, the diagonal lines appear to be broken due to an optical illusion. This phenomenon is called the Poggendorf illusion, an optical illusion in which the position of a diagonal line cut off by a thick element in the middle is misperceived.
It doesn't use diagonal lines like before, but it looks more unstable because it moves upward instead of to the right. In addition, various versions of the logo are used in a jumbled manner on the official homepage, official accounts, etc. where the logo is exposed. Musk likes diagonal lines and overlapping. I think I should be reassured that at least the minimum design details were paid attention to in Musk World, which is creating its own identity.
