An example is the serpent eating its own tail as a symbol of the eternal return, Ouroboros; and another is the eight-banded star.
On September 10, 2012, Obsidian's webpage began teasing about a brand new game (entitled "Project X"), it initially was a number 4 encircled by an Ouroboros.
The games logo uses the Ouroboros which symbolizes self-reflexivity, cyclicality, re-creation, and things beginning anew as soon as they end similar to the phoenix.
The cover of the album pictures an Ouroboros, with a vulture's head instead of a serpent, which was made to symbolise greed.
Additionally, two of his songs appear on the movie's soundtrack, them being Ouroboros (credited as Oneohtrix Point Never, previously released on Returnal) and Bling Ring Suite (credited as Brian Reitzell and Daniel Lopatin).
