from whence doth my finger come
the limits of thine eyes express 

I feel like you might have grabbed the wrong bag of mushrooms when you made dinner.

I also played a little bit with my visual field. Seeing my finger go out of it and not being able to describe how where my finger goes looks like is similar intriguing.

I feel like there’s some poetry in there for @plebpoet about the observable universe and how limited our interfaces to experience it are.

Yep. It's probably two functions that are so highly correlated that they activate similar feelings.
