Stratum 1

Make a grid or find a grid. Do one thing or another thing inside each unit.

Stratum 1.1

Draw a uniform grid of 200 x 200 squares within 1 square meter. Open a telephone directory and read the numbers in order. For each square, starting in the upper-left corner, fill with blue paint if the number is even, fill with red paint if the number is odd.

Stratum 1.2

Draw a grid of 40 x 25 units. Find a coin and define one side as A and the other as B. For each square, starting in the upper-left corner, flip the coin. If it lands with side A up, draw a line from the lower left to the upper right. If side B lands up, draw a line from the upper left to the lower right.
