Since 1991, he creates environments hand crafted from found materials which function as symbolic settings for his "lectures."

[1] In his "lectures", Bock acts on "stages" built from tables, cupboards or multi-level wood constructions.

The objects are handmade or re-modeled accessories of the lecture, made out of clothing, electrical equipment such as hoovers and mixers, or "plastic diagrams" that illustrate his mathematical explanations.

The "lectures" are structured by different scenes in which Bock sometimes works with (non-professional) actors; frequently he plays pop songs or classical pieces from a record player.

Bock is represented by Galerie Klosterfelde, Berlin, Anton Kern Gallery, New York, and Regen Projects, Los Angeles.
