His stairway is a double helix - that is what you are referring to right?
Here a couple others that come to mind:
- There is a scene when one of the two guys is looking into a mirror in the apartment, and because of the angle it reflects the ceiling at, the beams look like an X shaped chromosome.
- In-valid / invalid
- Character Names of Vincent FREEMAN and EuGENE MORROW
There must be a ton of others I am missing.
Semi-OT - I love the way their keyboards sound in that movie. I want one that sounds that way. It's more like a thump instead of a click.
