A Python script that takes a B&W image and generates an illusion where lines bending create that image, it's based on a viral image that reads "I Can't Sleep", examples: https://imgur.com/a/1NT0BIe

"I Can't Sleep" Effect.py

 from PIL import *
# from IPython.display import display # uncomment if you are using Jupyter

im = Image.open(r"C:\Put_your_B&W_img_here.jpg")
outIm =  Image.new('RGB', im.size, color = 'white')
draw = ImageDraw.Draw(outIm)
gridSpacing = 5
lineThickness = int(gridSpacing/2)

for i in range(0,im.size[0],gridSpacing):
    for j in range(0,im.size[1],gridSpacing):
        draw.line((i, j, i+1, j-1), fill=0, width=lineThickness)
        r,_,_ = im.getpixel((i, j))
        if r > 125:
            draw.line((i-1, j-1, i+gridSpacing, j+gridSpacing), fill=0, width=lineThickness)
        else:
            draw.line((i+5, j, i-gridSpacing+4, j+gridSpacing+1), fill=0, width=lineThickness)

outIm.show()
# display(outIm) # use this instead if you are using Jupyter
