Analogue photocopiers were first used to copy an image and replicate it on the same machine. Later they developed into digital scanners that could copy an image, digitise it, store it and send it to another location, where the image would be reconstructed to reproduce an exact facsimile of the original. This process was also used with movie film and sound, when videos were digitised and streamed on computers. This combined technology and the DNA of Dustin Hoffman’s old surgical slippers and a half-eaten banana from Newfoundland is responsible for the first compact time-machines and transporters for people.
