After researching the work of Bruce Nauman I have identified several links which might relate and prove worthy of investigation.
These include Nauman's links to Irish existentialist playwright Samuel Beckett's works; for example Nauman credits Beckett in his performance film Slow Angle Walk (Beckett Walk) from 1968. A consideration of John Cleese's performance from  Monty Python's Ministry of Silly Walks which aired in 1970, might be interesting, as might another piece of work with a title taken from Beckett - Miroslaw Balka's powerful piece How it is, which was an installation for the Unilever Series in the Turbine Hall at the Tate Modern in 2009.
