This is “not a pipe”, a game-poem that plays with reformulation.
Starting from the obviousness for humans of the content of their perception,a “tutorial voice” leads us via instructions into a radical regression questionning perception altogether.
The the voice repeatedly stating it’s not being understood by “you” (the reader) points at another problematic human interface with reality: language.
After a few steps, it’s clear the reformulation - regression could be infinite. The poem neatly ends on a (somewhat sketchy) Borgessian note, where the viewer has switched position and is now viewed.
