Four letters in extended sequence yield the blueprint of the human body. With another 22 or more letters the human mind is beginning to be inscribed, byte by byte, on tiny areas of magnetic disks located and across the globe.

This paper analyses how Luke Robert Mason’s performance of “ESS [re]Code” alludes to the transhumanist concept of mind-uploading - an emulated performance of identity.
