Googling “memphis style symbols” gives no useful results, just poorly made stock art. The design of the site is not at all akin to the Memphis Group, which is characterized by a sense of whimsy and lack of gravity, clashing colors and dazzling patterns.

Regarding neumorphism, I’d bet that will be much like the “long shadow” trend of yore; an interesting style that is hyped until, a short time after, the appeal of the newness and uniqueness wears off completely.
