Huh, I just realized I’ve been doing a version of this for the last decade or so.

When I’m tired or distracted at work, I do a “magic eye” with my keyboard: I bow my head down close to the keys, then focus my eyes to infinity, and gradually bring my focus closer to “snap” to different focus depths.

When I worked in an office, my coworkers found this disconcerting. Really helps me reset though!
