This is the INGSOC logo from the book 1984 by George Orwell.
I think that this resembles the biggest idea from the book, the idea where the government INGSOC manipulates it's citizens, I think that this was what I have learned from the book most.
This was a vocab word, Atrophy means to wither away and this oreo resembles the state of withering away, like the black cookie part started to get smaller and smaller until it vanishes.
