It is accompanied by a soundtrack made by his wife, Michèle Bokanowski, and released on the 2003 CD album, L'Ange, by the label trAace.

His manner of treating filmic material is his research at the frontier of optical and visual arts, always in an "in-between" to create.

Bokanowski's experiments, with the aim of opening cinema to other expressive possibilities – for example the "warping" of objective lenses (though he prefers the term "subjective") – testify to purely mental visions that ignore conventional representations, affecting reality, transforming, and giving the viewer of his films new perceptual adventures.
