I was really astonished on the intricate detail in which it was done, being in similar line of work I could imagine the effort that was put on by Rembrandt, listen to this Rubo, I downloaded one of the works, etching, and when I have free time on my new laser machine I will scan this picture and convert it into STL file then try to duplicate every detail on this new machine, should be lot of fun, I'll post it once I have it done.
Sorry guys, I know it was little of topic but I couldn’t resist
