Here you will find a few round binary plots made on the AxiDraw. On paper with various colours, using different fineliners. Different number of bits and also different representations.
6 bits circles, white on black, in sequence

 6 bits so 2^{6} = 64 circles
 Black paper, white lines. Plotted twice for better visibility
 In sequence from the top left to the bottom right
 Dimensions: 15×15 cm
10 bits circles, black on white, in sequence

 10 bits so 2^{10} = 1024 circles
 Plotted on CANSON® XL® Bristol Bristolpaper A4.
 Black, pigmented fine liner.
 In sequence from the top left to the bottom right
 Dimensions: 19x19cm
Details of this plot. It shows that it isn’t printed: the starting points are a bit blacker because it always starts at the same position (three ‘ o clock).
8 bits circles, black on white, shuffled
 8 bits so 2^{8} = 256 circles
 Plotted on CANSON® XL® Bristol Bristolpaper A4.
 Black, pigmented fine liner.
 Shuffled, all circles are different
 Dimensions: 15×15 cm
Detail. You see the same imperfections as before..
8 bits circles to the side, orange on white, in sequence

 8 bits so 2^{8} = 256 circles
 Plotted on CANSON® XL® Bristol Bristolpaper A4.
 Orange fine liner.
 In sequence
 Shrinking circles to the side
 Dimensions: 12×12 cm
