Recently while surfing the internet I came across this post on imgur about supposedly named “Single unbroken line portraits”.

I thought this to be quite an interesting way to create an image and thought I would try it myself. However I am far too lazy to spend hours drawing squiggly lines all day! So I wrote a program that does it instead!!

This works by creating lines and varying the thickness based on the colour intensity at each point of the line.

Even better I made it work in colour as well by varying thickness by colour channel and using additive alpha blending with the colours.

Here is the code if anyone is interested!
