Arithmetik Garden by Sato Masahiko and Kiriyama Takashi is another work which was exhibited at ICC in Tokyo last year, this time as part of the Open Space. Users enter the garden with a numbered RFID smart card:
Passing through the gates (with the calculating formulas shown) starts the “garden’s” calculations of your number. When their sum becomes exactly 73, you are finished, and can leave the “garden.” “Arithmetik Garden” was created to substitute a concrete idea of calculation for our usual abstract one. Becoming numbers ourselves allows us to experience calculating and being calculated via the position of our own bodies in this space.
