These reconfigured typewriters are by Tauba Auerbach. Olivettis looks awesome to begin with, so these souped-up specimens take it to the next level. I can’t make sense of the altered readouts of these machines, but apparently there is a system at work:

Auerbach often bases her work on these sorts of solvable codes or systems. In one of her works, a series of reconfigured typewriters, she alters the keys so that their letters and symbols no longer correspond to what appears on the paper. The typewriters are painted with clues to the logic of their new operating systems; once each code is cracked, the machine becomes functional again. Link

She’ll show in the Whitney Museum in NYC until May 30th 2010.
