Every extra colour besides black and white enlarges the possibilities in an enormous way. So I hesitated to introduce a new colour paper: grey. Here I combined two binary patterns, the spaces between circles in black and the circles in white. Both 8 bits so 2⁸=256 different space and circle patterns. The variations are endless (one shuffled, the other not, in reverse order, etc etc) but that scares me a bit, so first both in sequence.

Two binary patterns, 6 bits, black and white on grey. A3

  • 6 bits, so 64 patterns
  • both patterns in sequence
  • A3, 27×27 cm
