Can anyone point me to such canvas or explain me how to create one?

This image was taken from a picture I have in my living room and it covers somthing like 10 cm square of the picture. That means the shapes are very small and thin (actually you can't see them if you draw away from the picture).
Is it even possible to create the shapes random?
