These scripts can generate grids of random dots with different colours, black and white noise, any pixel draws and patterns like a chess board.

I put some of these designs also on objects like t-shirt, hats, mugs, puzzles, pillows, buttons, etc. You can find them here: https://www.redbubble.com/people/Mmark94/shop?asc=u

Black and white noise black_and_white_noise.py

You can set the dimension of your grid. In the example there are grids of 10x10, 100x100 and 1000x1000

You can set a different probability for each colour. In the example I set probability 100:1, 10:1, 1:1, 1:10 and 1:100

You can also set a gradient of probability for each colour. black_and_white_noise_probabilities.py

You can set how much connectivity there is in the black and white noise. For example, high connectivity means that the probability of a square being one colour is greater if the previous square is the same colour (positive feedback). Low connectivity means that the probability of a square being one colour is greater if the previous square is a different colour (negative feedback). black_and_white_noise_probabilities.py

high connectivity

low connectivity

with different grid dimensions

You can choose as many colours as you like.

You can change the layout of the blocks; they can also have a frame.

You can also save a grid or draw it using 0 and 1 or as many colours as you want. draw_with_grid.py

You can also generate a pattern. In the example, I generated a chessboard pattern. chess_board.py

You can generate many other patterns. You can also create random patterns. Pattern_generator.py

You can also use trigonometric functions (cos(x), sin(x)) to generate a pattern.
