Most of the heliographs are nothing more than the repetition of the same image, whether a human figure, or a door, or a bidet: a reiteration necessary to describe ‘normal’ human conditions.
These could be seen as the equivalent, in music, of simple refrains, repeated over and over until the audience joins in, and forgets to escape. In other heliographs, there is total chaos, as where masses of people march in opposite or perpendicular directions, destined to crash, and they do. In still others, nonsensical doors open in succession into other spaces without a final exit, in an impossible architectural design; or highways go around in circles, again without exit. The two types of heliographs represent extremes of life, both being surrealistic and incomprehensible.
