(oc) I wrote an algorithm that transforms photos into mosaics 

This picture of David Bowie was created using a strange algorithm plotting system

Hey Imgur!
Some may have seen my previous post (Single line spiral drawing: http://imgur.com/gallery/qv1xc
paint by numbers generator: http://imgur.com/gallery/x4bXl and some more).After seeing cool robots that can draw like e-David I wanted to try it out myself. Since I can not afford an industrial robot I bought a simple plotter that can hold a pen and started programming. Because the plotter can hold only a pen it can only draw lines with a constant width, so there is not a lot of variety… not a very promising start. But after some time I came to love the simplicity of a simple line and utilized it in the drawings.
Here is a new algorithm that I recently made and I would like to hear what you think of it.
The algorithm divides the photos into small tiles and randomly selects a style for each tile, the result is a bit messy but still very recognizable. Especially when you squinch your eyes.

I will soon try to draw these with my plotter and see how it turns out on real paper.

All the images I use are under creative commons license or are free to use under modification.
This is a photo of David Bowie.

A photo of a homeless man. I like this result a lot, because there are still many small details that are preserved.

A portrait of Alicia Vikander

Leon the professional. My favorite movie!

Edit: Since some wrote me:
While I do sell drawing made with my plotter, I do not sell this one yet. I feel it requires still some fine tuning.
