Infinite Jest is a memento Harry Mason can find in Silent Hill: Shattered Memories. The memento is located in Lisa Garland's apartment, inside a music box in her bathroom. The memento is a ring with a skull-and-crossbones insignia and the word Ophelia written on the back.
- The ring is likely a reference to Shakespeare's play Hamlet and the character of Ophelia.
- The ring may also be a reference to David Foster Wallace's 1996 novel Infinite Jest, which features a video cassette of a movie so addicting that viewers will watch it repeatedly until they die. This could allude to Cheryl's repeated watching of the video tape of her and her father.
